AndroidManifest.xml

<uses-permission android:name="Permission name" />

I want to specify Permission individually instead of all at once

MainActivity.java

public class MainActivity extends Activity {
    private static final int REQUEST_CODE = 1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ...
        RuntimePermissionChecker.requestPermission(this, REQUEST_CODE, Manifest.permission.CAMERA);
    }
}

this

RuntimePermissionChecker.requestPermission(Activity activity, int requestCode, String requestPermission);

By adding to any place, the process of confirming the specified Permission is executed by specifying the Permission name you want to hear individually in the above third argument (String requestPermission). (In the above case, the camera permission confirmation screen will be displayed.)

Supplement

I want to execute the process when all Permission is permitted

In that case, [onRequestPermissionsResult](https://developer.android.com/reference/android/app/Activity.html#onRequestPermissionsResult(int, java.lang.String [], int [])) as shown in the following example. Makes the process execute when the callback of is called.

MainActivity.java

public class MainActivity extends Activity {
    private static final int REQUEST_CODE = 1;

    @Override
    public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
        if (requestCode != REQUEST_CODE)
            return;
        if(!RuntimePermissionChecker.existConfirmPermissions(this)){
            // write features you want to execute.
        }
    }
}

this

RuntimePermissionChecker.existConfirmPermissions(Activity activity);

Will be ture </ font> if there are still permissions to listen to.

RuntimePermissionChecker.hasSelfPermission(Activity activity, String requestPermission);
