Android M 权限关闭我的应用程序

Question

我在登录屏幕上检查所需的权限。该对话框显示询问我需要的 4 个权限。一切都很好，但是当对话框出现时，背景变黑并且我的应用程序关闭(不会崩溃，只是关闭)。当我完成选择权限后，我再次打开应用程序，它会从停止的地方继续运行。如何在显示权限对话框时让应用程序继续运行？我使用一个类来检查权限并在登录 Activity 中调用它。

类(class):

public abstract class RuntimePermissionsActivity extends AppCompatActivity {
private SparseIntArray mErrorString;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    mErrorString = new SparseIntArray();
}

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults){
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    int permissionCheck = PackageManager.PERMISSION_GRANTED;
    for (int permission : grantResults){
        permissionCheck = permissionCheck + permission;
    }
    if ((grantResults.length>0) && permissionCheck == PackageManager.PERMISSION_GRANTED){
        onPermissionsGranted(requestCode);
    }
    else {

                Intent intent = new Intent();
                intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
                intent.addCategory(Intent.CATEGORY_DEFAULT);
                intent.setData(Uri.parse("package:" + getPackageName()));
                intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
                intent.addFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
                startActivity(intent);
    }
}

public void requestAppPermissions(final String[] requestedPermissions, final int requestCode){
    int stringId = 0;
    mErrorString.put(requestCode, stringId);
    int permissionCheck = PackageManager.PERMISSION_GRANTED;
    boolean shouldShowRequestPermissionRationale = false;
    for (String permission : requestedPermissions){
        permissionCheck = permissionCheck + ContextCompat.checkSelfPermission(this, permission);
        shouldShowRequestPermissionRationale = ActivityCompat.shouldShowRequestPermissionRationale(this, permission);
    }
    if(permissionCheck != PackageManager.PERMISSION_GRANTED){
        if(shouldShowRequestPermissionRationale){
                    ActivityCompat.requestPermissions(RuntimePermissionsActivity.this, requestedPermissions, requestCode);
        }
        else {
            ActivityCompat.requestPermissions(this, requestedPermissions, requestCode);
            Toast.makeText(RuntimePermissionsActivity.this, "Please relaunch the application in order for the changes to take effect!", Toast.LENGTH_LONG).show();
        }
    }
    else {
        onPermissionsGranted(requestCode);
    }

}
public abstract void onPermissionsGranted(int requestCode);
}

登录 Activity 调用:

LoginActivity.super.requestAppPermissions(new
            String[]{Manifest.permission.READ_CONTACTS, Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION,
            Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}, REQUEST_PERMISSIONS);

我遇到了同样的问题，请检查您的 list 文件中是否有 Activity android:noHistory="true"。
