Android：実行時にカスタム権限を要求する

Question

Android Marshmallowでユーザ定義のカスタム実行時アクセス権をリクエストする方法について、誰かが洞察を伝えることができますか？私は読み取り権限を持っているカスタムコンテンツプロバイダと、カスタムコンテンツプロバイダを使ってデータにアクセスしようとしている別のアプリケーションに取り組んでいます。

Answer 1

私は個人的には許可ライブラリを使用することをお勧めします。代わりに、大規模な定型コードの彼らが効果的になる傾向があり、コードは非常に正確である

それは私の作品。このPermissionsDispatcher

@RuntimePermissions 
public class MainActivity extends AppCompatActivity { 
    //sepcify permissions here 
    @NeedsPermission(Manifest.permission.CAMERA) 
    void showCamera() { 
     //work after permission is granted 
    } 

    @OnShowRationale({Manifest.permission.READ_CONTACTS, Manifest.permission.WRITE_CONTACTS}) 
    void showRationaleForCamera(final PermissionRequest request) { 
     new AlertDialog.Builder(this) 
      .setMessage(R.string.permission_camera_rationale) 
      .setPositiveButton(R.string.button_allow, (dialog, button) -> request.proceed()) 
      .setNegativeButton(R.string.button_deny, (dialog, button) -> request.cancel()) 
      .show(); 
    } 

    @OnPermissionDenied({Manifest.permission.READ_CONTACTS, Manifest.permission.WRITE_CONTACTS}) 
    void showDeniedForCamera() { 
     //works when permissions denied 
     Toast.makeText(this, R.string.permission_camera_denied, Toast.LENGTH_SHORT).show(); 
    } 

    @OnNeverAskAgain({Manifest.permission.READ_CONTACTS, Manifest.permission.WRITE_CONTACTS}) 
    void showNeverAskForCamera() { 
     Toast.makeText(this, R.string.permission_camera_neverask, Toast.LENGTH_SHORT).show(); 
    } 
}
