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，它从停止的地方继续运行。在显示权限对话框时，如何让应用程序继续运行？我使用 class 检查权限并在登录 activity.

中调用它

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);

在任何 Activity 中实施权限的示例。

SampleActivity.java

public class SampleActivity extends AppCompatActivity{
    private final int PERMISSION_CODE = 1;
    Button button;
    @override
    onCreate(Bundle savedInstance){
        super.onCreate(savedInstance);
        setContentView(R.layout.your_layout);
        button = (Button)findViewById(R.id.button);
        button.setOnClickListener(new OnClickListener(){
            @override
            public void onClick(View view){
                requestPermissionAndContinue();
            }
        });
        //remaining code to continue using the app
        //your actual code should also be in this same class
    }

    private void requestPermissionAndContinue(){
        if(ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED){
            if(ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.READ_CONTACTS)){
                Log.e(TAG, "permission denied, show dialog");
            }else{
                ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_CONTACTS}, PERMISSION_CODE);
            }
        }else{
            accessContacts();
        }
    }

    private void accessContacts(){
        //your code once you receive permission
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        if(grantResults.length > 0 && permissions[0]==PackageManager.PERMISSION_GRANTED){
            accessContacts();
        }else{
             //redirect to settings page or ask permission again
        }
    }
}

Answer 2

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

Answer 3

同样的问题。

ankit jain 在赛道上。删除 android:noHistory="true" 修复了 N.Park 问题。

虽然在我的例子中我需要那个值是真的，或者至少是行为（我有一个 SplashScreen，我在其中管理权限，并且在继续之后，我希望 Activity我的堆栈）。

所以：

我删除了行android:noHistory="true"
在activity我管理权限没有问题
之后，我进入下一个activity：

intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK );

Answer 4

只写几行代码：

 final int requestCode=100;
 if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M ) {
     String[] per = {Manifest.permission.READ_CONTACTS};
     requestPermissions(per, requestCode);

     if (ActivityCompat.checkSelfPermission(CollectZone.this, Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) {
         // recall permission until is not permitted
     } else { 
         // write execution code here   
     }
 }

Answer 5

从 Android 清单文件的相应 RuntimePermissionsActivity 标记中删除 android:noHistory="true" 属性解决了该问题。
