android.os.FileUriExposedException：file.jpgはClipData.Item.getUri（）を介してアプリを超えて公開されます

カメラを開いて写真を撮るボタンを試してみます。私のコードはここにあります

また、onclickメソッドでstartActivityForResultに問題があり、インポートJava.text.SimpleDateFormat;も例外ランタイムでジャンプします。buildtoolsversionSDK 25で作業しています

FileProviderを使用するソリューションの他に、これを回避する別の方法があります。簡単に言えば

 StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
 StrictMode.setVmPolicy(builder.build());

application.onCreate（）メソッドで。このようにして、VMはファイルURIの露出を無視します。

Add the below code where the SharingIntent called:-

if(Build.VERSION.SDK_INT>=24){
                    try{
                        Method m = StrictMode.class.getMethod("disableDeathOnFileUriExposure");
                        m.invoke(null);
                        shareImage(Uri.fromFile(new File(Path)));
                    }catch(Exception e){
                        e.printStackTrace();
                    }
                }
