MultiPermission V2 With Rebus Permission

Example Multi Check Permissions. Request Permissions at same time, I recommend to use this step on your First Activity, now i use it on PermissionActivity :

Step 1.

Add maven jitpack.io and dependencies in build.gradle (Project) :

// build.gradle project
allprojects {
  repositories {
    ...
    maven { url 'https://jitpack.io' }
  }
}

// build.gradle app/module
dependencies {
  ...
  implementation 'com.github.gzeinnumer:EasyExternalDirectoryAndroid:2.2.0'
}

Step 2.

Manifest. add permission ke file manifest. I recommend to add requestLegacyExternalStorage=true if you using Android 10.

<manifest >

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

    <application
        android:requestLegacyExternalStorage="true">

    </application>

</manifest>

Step 3.

Add array permission that you need :

First Activity. put request permission at your first activity, now i use it on PermissionActivity.

public class PermissionActivity extends AppCompatActivity {

    PermissionEnum[] permissions = new PermissionEnum[]{
            PermissionEnum.WRITE_EXTERNAL_STORAGE,
            PermissionEnum.READ_EXTERNAL_STORAGE
    };

    ...

}

Step 4.

Add function checkPermissions to check permission on app, if permission not granted than popup will show and ask to Allow. Please click allow :

public class PermissionActivity extends AppCompatActivity {

    ...

    //TYPE 1
    private void checkPermissions() {
        boolean isAllGranted = FGPermission.getPermissionResult(this, permissions);

        if (isAllGranted){
            onSuccessCheckPermitions();
        } else {
            Toast.makeText(this, "Permission Required", Toast.LENGTH_SHORT).show();
        }
    }

    //TYPE 2 if you want to know which permission that Granted or Denied. use this
    private void checkPermissions2() {
        FGPermission.getPermissionResult(this, permissions, new FGPermission.CallBackPermission() {
            @Override
            public void result(boolean isAllGranted, List<PermissionsResult> listPermissions) {
                Log.d(TAG, "result: "+isAllGranted);
                for (int i = 0; i < listPermissions.size(); i++) {
                    Log.d(TAG, "result: "+listPermissions.toString());
                }
                if (isAllGranted){
                    onSuccessCheckPermitions();
                } else {
                    Toast.makeText(getApplicationContext(), "Permission Required", Toast.LENGTH_SHORT).show();
                }
            }
        });
    }

    ...

}

Step 5.

You can check all permition are granted or not with function onRequestPermissionsResult, if granted you can run your code :

public class PermissionActivity extends AppCompatActivity {

    ...

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        PermissionManager.handleResult(this, requestCode, permissions, grantResults);

        checkPermissions();
    }

    ...

}

Step 6.

Add action to function onSuccessCheckPermitions :

public class PermissionActivity extends AppCompatActivity {

    ...

    private void onSuccessCheckPermitions() {

        startActivity(new Intent(getApplicationContext(), MainActivity.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK));

    }

}

notes.

• I always use this method to get permition for all Libray that i made.
• You can modif body of function onSuccessCheckPermitions.

Step 7.

Add function checkPermissions in onCreate to check permission everytime app running :

public class PermissionActivity extends AppCompatActivity {

    ...

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ...

        FGPermission.checkPermissions(this, permissions);

        checkPermissions();
    }

    ...

}

Step 8.

Fullcode will be like this :

public class PermissionActivity extends AppCompatActivity {

    private static final String TAG = "PermissionActivity";

    PermissionEnum[] permissions = new PermissionEnum[]{
            PermissionEnum.WRITE_EXTERNAL_STORAGE,
            PermissionEnum.READ_EXTERNAL_STORAGE
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_permission);

        FGPermission.checkPermissions(this, permissions);

        checkPermissions();
    }

    //TYPE 1
    private void checkPermissions() {
        boolean isAllGranted = FGPermission.getPermissionResult(this, permissions);

        if (isAllGranted){
            onSuccessCheckPermitions();
        } else {
            Toast.makeText(this, "Permission Required", Toast.LENGTH_SHORT).show();
        }
    }

    //TYPE 2
    private void checkPermissions2() {
        FGPermission.getPermissionResult(this, permissions, new FGPermission.CallBackPermission() {
            @Override
            public void result(boolean isAllGranted, List<PermissionsResult> list) {
                Log.d(TAG, "result: "+isAllGranted);
                for (int i = 0; i < list.size(); i++) {
                    Log.d(TAG, "result: "+list.toString());
                }
                if (isAllGranted){
                    onSuccessCheckPermitions();
                } else {
                    Toast.makeText(getApplicationContext(), "Permission Required", Toast.LENGTH_SHORT).show();
                }
            }
        });
    }

    private void onSuccessCheckPermitions() {
        Log.d(TAG, "onSuccessCheckPermitions: S");
        startActivity(new Intent(getApplicationContext(), PermissionActivity.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK));
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        PermissionManager.handleResult(this, requestCode, permissions, grantResults);

        checkPermissions();
    }
}

Step 9.

Request Permission 1	Request Permission 2	If all permission granted Toast AllGranted will show
