Android 6.0の複数の権限
私はAndroid 6.0が新しい許可を持っていることを知っています、そして私は私がこのような何かでそれらを呼び出すことができることを知っています
if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) !=
PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this,
new String[] {
Manifest.permission.WRITE_EXTERNAL_STORAGE
}, PERMISSION_WRITE_STORAGE);
}
今日、連絡先、SMS、カメラの3つの権限が必要なGoogleアプリを見ました。 1〜3ページ目を作成し、それらを同時に呼び出してアクティブにします。
SMS、カメラ、連絡先、ストレージなど、4つのアクセス許可を同時に有効にしてアクティブにする方法を教えてもらえますか。
例（Googleアプリの名前を忘れた場合:(）
アプリにはSMS、連絡先、カメラが必要です
アプリは私に尋ねた（そしてダイアログ1-3ページを作った）SMSをアクティブにし、連絡先をアクティブにしてからカメラ。それで、このGoogleアプリは3つの必要な許可すべてを一緒に呼び出していました、そして、私の質問は私が同じことをどうやって達成することができるかということです。
ActivityCompat.requestPermissions(...)呼び出しに4つすべての許可を含めるだけで、Androidは自動的にそれらを一緒にページングします。
私は複数の権限をチェックし、それらのいずれかが付与されていないかどうかを確認するためのヘルパーメソッドがあります。
public static boolean hasPermissions(Context context, String... permissions) {
if (context != null && permissions != null) {
for (String permission : permissions) {
if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
return false;
}
}
}
return true;
}
またはコトリンで：
fun hasPermissions(context: Context, vararg permissions: String): Boolean = permissions.all {
ActivityCompat.checkSelfPermission(context, it) == PackageManager.PERMISSION_GRANTED
}
それからちょうどそれをすべての許可に送ってください。 Androidは必要なものだけを要求します。
// The request code used in ActivityCompat.requestPermissions()
// and returned in the Activity's onRequestPermissionsResult()
int PERMISSION_ALL = 1;
String[] PERMISSIONS = {
Android.Manifest.permission.READ_CONTACTS,
Android.Manifest.permission.WRITE_CONTACTS,
Android.Manifest.permission.WRITE_EXTERNAL_STORAGE,
Android.Manifest.permission.READ_SMS,
Android.Manifest.permission.CAMERA
};
if(!hasPermissions(this, PERMISSIONS)){
ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
}
これは複数の許可要求を伴う詳細な例です： -
アプリは起動時に2つの権限が必要です。 SEND_SMSとACCESS_FINE_LOCATION（どちらもmanifest.xmlに記載されています）。
私は Support Library v4 を使用しています。これはAndroid以前のマシュマロを処理するために用意されているので、ビルドバージョンを確認する必要はありません。
アプリが起動するとすぐに、複数の権限を同時に要求します。両方の権限が付与されている場合は通常のフローになります。
public static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if(checkAndRequestPermissions()) {
// carry on the normal flow, as the case of permissions granted.
}
}
private boolean checkAndRequestPermissions() {
int permissionSendMessage = ContextCompat.checkSelfPermission(this,
Manifest.permission.SEND_SMS);
int locationPermission = ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION);
List<String> listPermissionsNeeded = new ArrayList<>();
if (locationPermission != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.ACCESS_FINE_LOCATION);
}
if (permissionSendMessage != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.SEND_SMS);
}
if (!listPermissionsNeeded.isEmpty()) {
ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]),REQUEST_ID_MULTIPLE_PERMISSIONS);
return false;
}
return true;
}
ContextCompat.checkSelfPermission（）、ActivityCompat.requestPermissions（）、ActivityCompat.shouldShowRequestPermissionRationale（）はサポートライブラリの一部です。
1つ以上の権限が付与されていない場合、ActivityCompat.requestPermissions（）は権限を要求し、制御はonRequestPermissionsResult（）コールバックメソッドに進みます。
OnRequestPermissionsResult（）コールバックメソッドのshouldShowRequestPermissionRationale（）フラグの値を確認する必要があります。
ケースは2つしかありません。 -
ケース1： - ユーザーが[Deny]アクセス許可をクリックするたびに（初回を含む）、trueが返されます。そのため、ユーザーが拒否した場合は、より多くの説明を表示して再度質問することができます。
ケース2： - ユーザーが「二度と質問しない」を選択した場合のみ、falseが返されます。この場合、制限された機能を続行し、ユーザーがより多くの機能の設定から権限を有効にするようにガイドすることも、アプリにとって権限が簡単な場合は設定を終了することもできます。
ケース-1
CASE-2

簡単です、こうしてください
private static final int REQUEST_READ_PHONE_STATE = 110 , REQUEST_ACCESS_FINE_LOCATION = 111, REQUEST_WRITE_STORAGE = 112;
あなたのonCreateに
//request permission
boolean hasPermissionPhoneState = (ContextCompat.checkSelfPermission(getApplicationContext(),
Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_GRANTED);
if (!hasPermissionPhoneState) {
ActivityCompat.requestPermissions(LoginActivity.this,
new String[]{Manifest.permission.READ_PHONE_STATE},
REQUEST_READ_PHONE_STATE);
}
boolean hasPermissionLocation = (ContextCompat.checkSelfPermission(getApplicationContext(),
Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED);
if (!hasPermissionLocation) {
ActivityCompat.requestPermissions(LoginActivity.this,
new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
REQUEST_ACCESS_FINE_LOCATION);
}
boolean hasPermissionWrite = (ContextCompat.checkSelfPermission(getApplicationContext(),
Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED);
if (!hasPermissionWrite) {
ActivityCompat.requestPermissions(LoginActivity.this,
new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
REQUEST_WRITE_STORAGE);
}
それから結果を確認してください
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode)
{
case REQUEST_READ_PHONE_STATE: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
{
Toast.makeText(LoginActivity.this, "Permission granted.", Toast.LENGTH_SHORT).show();
//reload my activity with permission granted or use the features what required the permission
finish();
startActivity(getIntent());
} else
{
Toast.makeText(LoginActivity.this, "The app was not allowed to get your phone state. Hence, it cannot function properly. Please consider granting it this permission", Toast.LENGTH_LONG).show();
}
}
case REQUEST_ACCESS_FINE_LOCATION: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
{
Toast.makeText(LoginActivity.this, "Permission granted.", Toast.LENGTH_SHORT).show();
//reload my activity with permission granted or use the features what required the permission
finish();
startActivity(getIntent());
} else
{
Toast.makeText(LoginActivity.this, "The app was not allowed to get your location. Hence, it cannot function properly. Please consider granting it this permission", Toast.LENGTH_LONG).show();
}
}
case REQUEST_WRITE_STORAGE: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
{
Toast.makeText(LoginActivity.this, "Permission granted.", Toast.LENGTH_SHORT).show();
//reload my activity with permission granted or use the features what required the permission
finish();
startActivity(getIntent());
} else
{
Toast.makeText(LoginActivity.this, "The app was not allowed to write to your storage. Hence, it cannot function properly. Please consider granting it this permission", Toast.LENGTH_LONG).show();
}
}
}
}
複数の権限を要求するための私のハンドラクラス。 fullを使って/ /をチェックできます ここ

return;
}
requestUnGrantedPermissions(permissions, requestCode);
}
private boolean needRequestRuntimePermissions() {
return Build.VERSION.SDK_INT >= Build.VERSION_CODES.M;
}
private void requestUnGrantedPermissions(String[] permissions, int requestCode) {
String[] unGrantedPermissions = findUnGrantedPermissions(permissions);
if (unGrantedPermissions.length == 0) {

以下の方法論は
- 動的に許可を求める。
- ユーザーが許可を拒否した場合にAlertDialogを表示する
- ユーザーが許可を受け入れるまでループする
パーミッションメソッド用の「静的」クラスを作成します
public class PermissionsUtil {
public static final int PERMISSION_ALL = 1;
public static boolean doesAppNeedPermissions(){
return Android.os.Build.VERSION.SDK_INT > Build.VERSION_CODES.Lollipop_MR1;
}
public static String[] getPermissions(Context context)
throws PackageManager.NameNotFoundException {
PackageInfo info = context.getPackageManager().getPackageInfo(
context.getPackageName(), PackageManager.GET_PERMISSIONS);
return info.requestedPermissions;
}
public static void askPermissions(Activity activity){
if(doesAppNeedPermissions()) {
try {
String[] permissions = getPermissions(activity);
if(!checkPermissions(activity, permissions)){
ActivityCompat.requestPermissions(activity, permissions,
PERMISSION_ALL);
}
} catch(Exception e) {
e.printStackTrace();
}
}
}
public static boolean checkPermissions(Context context, String... permissions){
if (Android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null &&
permissions != null) {
for (String permission : permissions) {
if (ContextCompat.checkSelfPermission(context, permission) !=
PackageManager.PERMISSION_GRANTED) {
return false;
}
}
}
return true;
}
}
MainActivity.Javaの場合
private void checkPermissions(){
PermissionsUtil.askPermissions(this);
}
@Override
public void onRequestPermissionsResult(int requestCode,
@NonNull String[] permissions,
@NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case PermissionsUtil.PERMISSION_ALL: {
if (grantResults.length > 0) {
List<Integer> indexesOfPermissionsNeededToShow = new ArrayList<>();
for(int i = 0; i < permissions.length; ++i) {
if(ActivityCompat.shouldShowRequestPermissionRationale(this, permissions[i])) {
indexesOfPermissionsNeededToShow.add(i);
}
}
int size = indexesOfPermissionsNeededToShow.size();
if(size != 0) {
int i = 0;
boolean isPermissionGranted = true;
while(i < size && isPermissionGranted) {
isPermissionGranted = grantResults[indexesOfPermissionsNeededToShow.get(i)]
== PackageManager.PERMISSION_GRANTED;
i++;
}
if(!isPermissionGranted) {
showDialogNotCancelable("Permissions mandatory",
"All the permissions are required for this app",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
checkPermissions();
}
});
}
}
}
}
}
}
private void showDialogNotCancelable(String title, String message,
DialogInterface.OnClickListener okListener) {
new AlertDialog.Builder(this)
.setTitle(title)
.setMessage(message)
.setPositiveButton("OK", okListener)
.setCancelable(false)
.create()
.show();
}
私のアプローチはNicksの答えに基づいており、うまくいけば複数の（2つだけではなく必要なだけ）許可にもう少し使いやすいです。単一責任PermissionsHelperクラスを追加することを提案します。

super.onCreate(savedInstanceState);
checkPermissions();
//any other code
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
permissionsHelper.onRequestPermissionsResult(this, requestCode, permissions, grantResults);
}
private void checkPermissions() {
permissionsHelper = new PermissionsHelper();
permissionsHelper.checkAndRequestPermissions(this,
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.ACCESS_COARSE_LOCATION);
}
これが誰かに役立つことを願っています。
複数の権限を要求する回答に問題はありませんが、複数の権限の結果コードはあまり洗練されて実装されていないため、間違った権限の結果がチェックされる可能性があります。
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)は複数のパーミッション結果をチェックするためのひどいロジックです、私はなぜグーグルがそのようなひどいコードを実装したのかわかりません。
特にあなたが複数の権限をチェックするときそれはめちゃくちゃです。 CAMERA、ACCESS_FINE_LOCATIONおよびACCESS_NETWORK_STATEを要求したとしましょう。
あなたはACCESS_FINE_LOCATIONをチェックする必要がありますが、ユーザは最初の実行でのみCAMERAを与えられ、あなたはgrantResults[1]をチェックしますが2番目の実行でACCESS_FINE_LOCATIONはインデックス0のパーミッションになります。許可結果ロジック。
どちらを使うべきか
int size = permissions.length;
boolean locationPermissionGranted = false;
for (int i = 0; i < size; i++) {
if (permissions[i].equals(Manifest.permission.ACCESS_FINE_LOCATION)
&& grantResults[i] == PackageManager.PERMISSION_GRANTED) {
locationPermissionGranted = true;
}
}
それとももっと単純なもの
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
== PackageManager.PERMISSION_GRANTED) {
// Do something ...
}
onPermissionRequestResultメソッドで。

短くて甘い：）。私が信じていること.
int PERMISSION_ALL = 1;
String[] PERMISSIONS = {Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}; // List of permissions required
public void askPermission()
{
for (String permission : PERMISSIONS) {
if (ActivityCompat.checkSelfPermission(this, permission) != PackageManager.PERMISSION_GRANTED) {
requestPermissions(PERMISSIONS, PERMISSION_ALL);
return;
}
}
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions,
int[] grantResults) {
switch (requestCode) {
case 1:{
if(grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED && grantResults[1] == PackageManager.PERMISSION_GRANTED){
//Do your work.
} else {
Toast.makeText(this, "Until you grant the permission, we cannot proceed further", Toast.LENGTH_SHORT).show();
}
return;
}
}
長く複雑な答えをすべて見た後。この答えを投稿してほしい。
RxPermission は1行のコードで許可を求めるために現在広く使われているライブラリです。
RxPermissions rxPermissions = new RxPermissions(this);
rxPermissions
.request(Manifest.permission.CAMERA,
Manifest.permission.READ_PHONE_STATE)
.subscribe(granted -> {
if (granted) {
// All requested permissions are granted
} else {
// At least one permission is denied
}
});
build.gradleを追加
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
dependencies {
implementation 'com.github.tbruyelle:rxpermissions:0.10.1'
implementation 'com.jakewharton.rxbinding2:rxbinding:2.1.1'
}
これは簡単ではないですか？
Multiple Permissions at Onceの簡単なコードの実装に成功しました。以下の手順に従ってください1：Utility.Javaクラスを以下のようにします。
public class Utility {
public static final int MY_PERMISSIONS_REQUEST = 123;
@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
public static boolean checkPermissions(Context context, String... permissions) {
if (Android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
for (String permission : permissions) {
if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale((Activity) context, permission)) {
ActivityCompat.requestPermissions((Activity) context, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.CALL_PHONE,Manifest.permission.GET_ACCOUNTS}, MY_PERMISSIONS_REQUEST);
} else {
ActivityCompat.requestPermissions((Activity) context, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.CALL_PHONE,Manifest.permission.GET_ACCOUNTS}, MY_PERMISSIONS_REQUEST);
}
return false;
}
}
}
return true;
}
}
2：今すぐ電話
boolean permissionCheck = Utility.checkPermissions(this, Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.CALL_PHONE, Manifest.permission.GET_ACCOUNTS);
あなたのActivity onCreate（）で、またはあなたの論理に従って。
3：特定のタスクに対する操作を実行する前に許可を確認する
if (permissionCheck) {
performTaskOperation();//this method what you need to perform
} else {
Toast.makeText(this, "Need permission ON.", Toast.LENGTH_SHORT).show();
}
4：以下のようにActivityにonRequestPermissionsResult（）メソッドを実装します
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
case Utility.MY_PERMISSIONS_REQUEST:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
if (userChoosenTask.equals("STORAGE"))
performTaskOperation();//this method what you need to perform
}
break;
}
}
複数の許可を求める簡単な方法
https://github.com/sachinvarma/EasyPermission
追加する方法：
repositories {
maven { url "https://jitpack.io" }
}
implementation 'com.github.sachinvarma:EasyPermission:1.0.1'
許可を求める方法：
List<String> permission = new ArrayList<>();
permission.add(EasyPermissionList.READ_EXTERNAL_STORAGE);
permission.add(EasyPermissionList.ACCESS_FINE_LOCATION);
new EasyPermissionInit(MainActivity.this, permission);

これは、Googleのgithubのランタイム権限の例にあります。
private static String[] PERMISSIONS_CONTACT = {Manifest.permission.READ_CONTACTS,
Manifest.permission.WRITE_CONTACTS};
private static final int REQUEST_CONTACTS = 1;
ActivityCompat.requestPermissions(this, PERMISSIONS_CONTACT, REQUEST_CONTACTS);
このようにヘルパーを使用してください（パーミッション名は関係ありません）。
public class MyPermission {
private static final int PERMISSION_REQUEST_ALL = 127;
private MainActivity mMainActivity;
MyPermission(MainActivity mainActivity) {
mMainActivity = mainActivity;
}
public static boolean hasPermission(String permission, Context context) {
if (isNewPermissionModel()) {
return (ActivityCompat.checkSelfPermission(context, permission) == PackageManager.PERMISSION_GRANTED);
}
return true;
}
private static boolean hasPermissions(Context context, String... permissions) {
if (isNewPermissionModel() && context != null && permissions != null) {
for (String permission : permissions) {
if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
return false;
}
}
}
return true;
}
private static boolean shouldShowRationale(Activity activity, String permission) {
return isNewPermissionModel() && ActivityCompat.shouldShowRequestPermissionRationale(activity, permission);
}
private static boolean isNewPermissionModel() {
return VERSION.SDK_INT > VERSION_CODES.Lollipop_MR1;
}
/**

*/
void checkAll() {
//check dangerous permissions, make request if need (Android will ask only for the ones it needs)
String[] PERMISSIONS = {
permission.READ_CALENDAR,
permission.ACCESS_COARSE_LOCATION
};
if (!hasPermissions(mMainActivity, PERMISSIONS)) {
ActivityCompat.requestPermissions(mMainActivity, PERMISSIONS, PERMISSION_REQUEST_ALL);
}
}
void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
if (requestCode == PERMISSION_REQUEST_ALL) {
if (grantResults.length > 0) {
//for not granted
for (int i = 0; i < permissions.length; i++) {
if (permissions[i].equals(permission.READ_CALENDAR)) {
if (grantResults[i] != PackageManager.PERMISSION_GRANTED) {
smartRequestPermissions(permission.READ_CALENDAR, R.string.permission_required_dialog_read_calendar);
}
} else if (permissions[i].equals(permission.ACCESS_COARSE_LOCATION)) {
if (grantResults[i] != PackageManager.PERMISSION_GRANTED) {
smartRequestPermissions(permission.ACCESS_COARSE_LOCATION, R.string.permission_required_dialog_access_coarse_location);
}
}
}
}
}
}
private void smartRequestPermissions(final String permissionName, int permissionRequiredDialog) {
if (shouldShowRationale(mMainActivity, permissionName)) {// If the user turned down the permission request in the past and chose the Don't ask again option in the permission request system dialog, this method returns false.
//Show an explanation to the user with action
mMainActivity.mSnackProgressBarManager.show(
new SnackProgressBar(
SnackProgressBar.TYPE_ACTION, mMainActivity.getString(permissionRequiredDialog)
)
.setAction("OK", new OnActionClickListener() {
@Override
public void onActionClick() {
checkAll();
}
})
.setSwipeToDismiss(true).setAllowUserInput(true)
, MainActivity.SNACKBAR_WARNING_DURATION
);
} // else do nothing
}
}
これが私の活動でやったことです。希望が役立つでしょう。カメラとマイクの許可を求めています。
public class ActiveCallActivity extends AppCompatActivity {
.....
private static final String cameraPermissionKey = "cameraPermission";
private static final String microphonePermissionkey = "microphonePermission";
private static ArrayList<String> permissionsQueue = new ArrayList<String>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
.....
// in ValidationCheckersAndValidators simply checking if have permission or not.
if(ValidationCheckersAndValidators.haveCameraPermission(this)) performHaveCameraPermissionLayout(); else performHaveNoCameraPermissionLayout();
if(ValidationCheckersAndValidators.haveMicrophonePermission(this)) performHaveMicrophonePermissionLayout(); else performHaveNoMicrophonePermissionLayout();
}
private void performHaveNoCameraPermissionLayout() {
.....
permissionsQueue.add(cameraPermissionKey);
}
private void performHaveNoMicrophonePermissionLayout() {
.....
permissionsQueue.add(microphonePermissionkey);
}
@Override
protected void onResume() {
super.onResume();
.....
passThroughPermissionsQueue();
}
private void passThroughPermissionsQueue() {
if(!permissionsQueue.isEmpty()) {
String permissionKey = permissionsQueue.remove(0);
switch (permissionKey) {
case cameraPermissionKey: {
ValidationCheckersAndValidators.requestForCameraPermission(this);
return;
}
case microphonePermissionkey: {
ValidationCheckersAndValidators.requestForMicrophonePermission(this);
return;
}
}
}
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch(requestCode) {
case cameraPermissionRequestCode: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
performHaveCameraPermissionLayout();
}
break;
}
case microphonePermissionRequestCode: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
performHaveMicrophonePermissionLayout();
}
break;
}
}
passThroughPermissionsQueue();
}
}
私はただ複数の要求を達成するために配列を使用します、それが誰かに役立つことを願っています。 （コトリン）

Dexter を使用できます
build.gradleに追加：
implementation 'com.karumi:dexter:5.0.0'
アクティビティで次のように使用します。
val requiredPermissions = when {
Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q -> listOf(Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.ACCESS_COARSE_LOCATION,
Manifest.permission.ACCESS_BACKGROUND_LOCATION)
else -> listOf(Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.ACCESS_COARSE_LOCATION)
}
Dexter.withActivity(this)
.withPermissions(
requiredPermissions
)
.withListener(object : MultiplePermissionsListener {
override fun onPermissionRationaleShouldBeShown(
permissions: MutableList<PermissionRequest>?,
token: PermissionToken?
) {
/* ... */
}
override fun onPermissionsChecked(report: MultiplePermissionsReport) =
if (report.isAnyPermissionPermanentlyDenied) {
toast("You should grant all permissions")
} else {
toast("All permissions granted")
// continue here if permission is a must
}).check()
// continue here if permission is not a must
