Android 6.0 Permission Error
Yes permissions have changed on Android M. Permissions are now requested at runtime as opposed to install time previous to Android M.
You can check out the docs here
This release introduces a new permissions model, where users can now directly manage app permissions at runtime. This model gives users improved visibility and control over permissions, while streamlining the installation and auto-update processes for app developers. Users can grant or revoke permissions individually for installed apps.
On your apps that target Android 6.0 (API level 23) or higher, make sure to check for and request permissions at runtime. To determine if your app has been granted a permission, call the new checkSelfPermission() method. To request a permission, call the new requestPermissions() method. Even if your app is not targeting Android 6.0 (API level 23), you should test your app under the new permissions model.
For details on supporting the new permissions model in your app, see Working with System Permissionss. For tips on how to assess the impact on your app, see Permissions Best Practices.
To check for permissions you have to check like this, taken from github
public class MainActivity extends SampleActivityBase
implements ActivityCompat.OnRequestPermissionsResultCallback {

I modified @Modge's code, in my case I needed to ask for IMEI permission and the best way to go is during runtime so i did this:
/**
* A loading screen after AppIntroActivity.
*/
public class LoadingActivity extends BaseActivity {
private static final int MY_PERMISSIONS_REQUEST_READ_PHONE_STATE = 0;
private TextView loading_tv2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_loading);
//trigger 'loadIMEI'
loadIMEI();
/** Fading Transition Effect */
overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
}
/**
* Called when the 'loadIMEI' function is triggered.
*/
public void loadIMEI() {
// Check if the READ_PHONE_STATE permission is already available.
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE)
!= PackageManager.PERMISSION_GRANTED) {
// READ_PHONE_STATE permission has not been granted.
requestReadPhoneStatePermission();
} else {
// READ_PHONE_STATE permission is already been granted.
doPermissionGrantedStuffs();
}
}
/**
* Requests the READ_PHONE_STATE permission.
* If the permission has been denied previously, a dialog will prompt the user to grant the
* permission, otherwise it is requested directly.
*/
private void requestReadPhoneStatePermission() {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.READ_PHONE_STATE)) {
// Provide an additional rationale to the user if the permission was not granted
// and the user would benefit from additional context for the use of the permission.
// For example if the user has previously denied the permission.
new AlertDialog.Builder(LoadingActivity.this)
.setTitle("Permission Request")
.setMessage(getString(R.string.permission_read_phone_state_rationale))

//re-request

MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
}
})
.setIcon(R.drawable.onlinlinew_warning_sign)
.show();
} else {
// READ_PHONE_STATE permission has not been granted yet. Request it directly.
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_PHONE_STATE},
MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
}
}
/**

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,

public void doPermissionGrantedStuffs() {

// Now read the desired content to a textview.
loading_tv2 = (TextView) findViewById(R.id.loading_tv2);
loading_tv2.setText(IMEINumber);
}
}
Hope this helps you or someone.
I did something like this :
if (checkSelfPermission(Manifest.permission.READ_PHONE_STATE)
!= PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[]{Manifest.permission.READ_PHONE_STATE},
PERMISSIONS_REQUEST_READ_PHONE_STATE);
} else {
setDeviceImei();
}
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions,
int[] grantResults) {
if (requestCode == PERMISSIONS_REQUEST_READ_PHONE_STATE
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
setDeviceImei();
}
}
private void setDeviceImei() {
mTelephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
//Code
.........
..............
}
How i will get List of Permission that i need to set at runtime..?
