Not able to launch Gallery from Android Instant app - android

I created an app which picks up images from images folder in emulator and displays selected image in my layout of application. When I converted my app to instant app, the same code that picks up images from image folder throws exception. I used runtime permissions READ_EXTERNAL_STORAGE.
My code:
private static final int PICK_IMAGE_REQUEST = 234;
Intent intent = new Intent();
intent.setType("*/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, PICK_IMAGE_REQUEST);
Exception thrown:
java.lang.SecurityException: Not allowed to start activity Intent {
act=android.intent.action.GET_CONTENT typ=*/* }
Code for runtime permissions:
private static final int REQUEST_WRITE_STORAGE = 112;
#TargetApi(Build.VERSION_CODES.JELLY_BEAN)
public boolean checkPermission()
{
int currentAPIVersion = Build.VERSION.SDK_INT;
if(currentAPIVersion>=android.os.Build.VERSION_CODES.M)
{
if (ActivityCompat.checkSelfPermission(MainActivity.this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale((Activity) MainActivity.this, Manifest.permission.READ_EXTERNAL_STORAGE)) {
Toast.makeText(MainActivity.this,"Permission Denied...",Toast.LENGTH_LONG).show();
} else {
ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, REQUEST_WRITE_STORAGE);
return true;
}
return false;
} else {
return true;
}
} else {
return true;
}
}
Can anyone help me in solving this issue?

Instant Apps are blocked from accessing some features that regular Android apps can access. The exception:
java.lang.SecurityException: Not allowed to start activity Intent...
Means you have found one such feature. In this case it is Intent.ACTION_GET_CONTENT which is not currently allowed. Support for additional features such as this may be introduced over time.
In addition, Instant Apps do not have access to read or write from external storage so requesting access to READ_EXTERNAL_STORAGE will also not work or throw an exception. See here for a list of permissions that are supported by Instant Apps.

Allow WRITE_SETTINGS permission with Android 11 from manifest

I have an application that is meant for "locked Android phones" meaning the application is the only application users will have access to on that phone and that is done using MySync.
Before the application had to support Android 11 (complieSdkVersion 30), the user was able to change screen brightness and other system settings from the application (Since the user did not have access to the settings app). But now the WRITE_SETTINGS and CHANGE_CONFIGURATION are deprecated and no longer have desirable effects.
I am aware that it is possible to prompt the user to accept the settings with this prompt:
boolean permission;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
permission = Settings.System.canWrite(context);
} else {
permission = ContextCompat.checkSelfPermission(context, Manifest.permission.WRITE_SETTINGS) == PackageManager.PERMISSION_GRANTED;
}
if (permission) {
initApp();
} else {
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
Intent intent = new Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS);
intent.setData(Uri.parse("package:" + context.getPackageName()));
startActivityForResult(intent, SettingsActivity.CODE_WRITE_SETTINGS_PERMISSION);
} else {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_SETTINGS}, SettingsActivity.CODE_WRITE_SETTINGS_PERMISSION);
}
}
But since the user does not have access to the settings application in my app eco-system, I can not give the user a prompt that would open up the settings and allow the user to stay in the settings.
Is there no way around this permission request and is there no way to do it on the manifest level or some other way?

App crashes when requesting permission

I'm using this code to request SMS permission before running the method SendSMS(string 1, string 2);
but my app crashes before permission request takes place.
What's missing?
final private int REQUEST_CODE = 101;
private void SendCreditSMS() {
if (ActivityCompat.checkSelfPermission(MainActivity.this, Manifest.permission.SEND_SMS)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(MainActivity.this,
new String[]{Manifest.permission.SEND_SMS}, REQUEST_CODE);
} else {
SendSMS("181", "رصيد");
}
}
Try this,
final private int REQUEST_CODE = 101;
private void SendCreditSMS() {
if (Build.VERSION.SDK_INT >= 23) {
if (ActivityCompat.checkSelfPermission(MainActivity.this, android.Manifest.permission.SEND_SMS)
!= PackageManager.PERMISSION_GRANTED)
{
ActivityCompat.requestPermissions(MainActivity.this,
new String[]{android.Manifest.permission.SEND_SMS}, REQUEST_CODE);
} else
{
SendSMS("181", "رصيد");
}
}
else{
SendSMS("181", "رصيد");
}
}
The problem may be due to the reason that you declared the activity in which you request permission(s) as with no history. To solve the problem remove
android:noHistory="true"
line from the associated activity's code block in AndroidManifest file. To have an activity with no history you can use other calls such as finishAndRemoveTask().
Try going to the application manager in your android device and select the app you are currently executing. Then check whether permissions are given by the device to use send_sms service in your device.

Requesting permissions in Android 6.0 (API level 23)

Is it necessary that requesting each dangerous permission it needs while the app is running Android 6.0 or higher?I have requested the following dangerous permissions,but there are only four dialogs.
The premissions
public static final String[] PERMISSIONS = new String[]{
android.Manifest.permission.CALL_PHONE,
android.Manifest.permission.WRITE_EXTERNAL_STORAGE,
android.Manifest.permission.READ_EXTERNAL_STORAGE,
android.Manifest.permission.ACCESS_COARSE_LOCATION,
android.Manifest.permission.ACCESS_FINE_LOCATION,
android.Manifest.permission.READ_PHONE_STATE,
android.Manifest.permission.WRITE_SETTINGS,
android.Manifest.permission.GET_ACCOUNTS,
android.Manifest.permission.CAMERA
};
The dialogs
1.Allow the app to make and manage phone calls?
2.Allow the app to access photos,media,and files on your device?
3.Allow the app to access this device's location?
4.Allow the app to access your contacts?
I cant get the permissions such as android.Manifest.permission.READ_PHONE_STATE,
android.Manifest.permission.WRITE_SETTINGS,
android.Manifest.permission.GET_ACCOUNTS,
android.Manifest.permission.CAMERA,neither code nor system setting.
Special Permissions
There are a couple of permissions that don't behave like normal and
dangerous permissions. WRITE_SETTINGS is
particularly sensitive, so most apps should not use them. If an app
needs one of these permissions, it must declare the permission in the
manifest, and send an intent requesting the user's authorization. The
system responds to the intent by showing a detailed management screen
to the user.
Demo
public class MainActivity extends AppCompatActivity {
Context context;
TextView textView;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
context = this;
textView = (TextView) findViewById(R.id.foodName);
textView.setText(getResources().getText(R.string.txt_name));
textView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
boolean result = true;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
result = Settings.System.canWrite(context);
Log.d("TAG", "Can Write Settings: " + result);
if (result) {
Toast.makeText(context, "Write allowed :-)", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(context, "Write not allowed :-(", Toast.LENGTH_LONG).show();
Intent intent = new Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS);
intent.setData(Uri.parse("package:" + context.getPackageName()));
startActivity(intent);
}
}
}
});
}
}

Android permissions READ_CONTACT [duplicate]

This question already has answers here:
Android permission doesn't work even if I have declared it
(11 answers)
Closed 6 years ago.
Why i get this message
if the i set the permission in the manifest file:
Thank you for any help.
You need request permission at runtime in android >= 6.0
https://developer.android.com/training/permissions/requesting.html
You have to grant permission in android version >=6.0 (Marshmallow and above).
For Android 6.0+, you have to request the permission at runtime as well as adding it to the manifest. So something like this added to your Activity onCreate();
List<String> permissions = new ArrayList<>();
permissions.add(Manifest.permission.READ_CONTACTS);
//...add any others you need to this arraylist
// Convert the List to an Array
String[] permissionsArray = permissions.toArray(new String[0]);
ActivityCompat.requestPermissions(getActivity(), permissionsArray, REQUEST_CODE);
//The REQUEST_CODE is just a integer that your callback method will check, set it to some number
Then override this method in your activity to check whether the request was granted or not
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
case REQUEST_CODE: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//Permission Granted, do your thing
} else {
//Permission denied, you can't do what you want to because user didn't give you permission
}
return;
}
}
See here for more info https://developer.android.com/training/permissions/requesting.html
Change your target sdk version to 22 in your app's build.gradle if you donot want to request the permission to the user at run time.
Else if you want to keep the target sdk version to 23 then you would need to request the permission from the user at run time as mentioned above by #wanpanman
Call this permission.
//Check permissions
public boolean reqPermission() {
if (!Permissions.checkPermission(this, Manifest.permission.READ_CONTACTS)) {
if (shouldShowRationale(Manifest.permission.READ_CONTACTS)) {
Snackbar.make(yourLayout, "Need to enable contact permission to use this feature. bla bla bla",
Snackbar.LENGTH_INDEFINITE)
.setAction(R.string.settings, new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent();
intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
Uri uri = Uri.fromParts("package", getPackageName(), null);
intent.setData(uri);
startActivity(intent);
}
})
.show();
return true;
} else {
Permissions.grantPermission(this, PERMISSION_REQUEST_CODE);
return true;
}
} else {
return false;
}
}
#TargetApi(Build.VERSION_CODES.M)
public boolean shouldShowRationale(String permission) {
return shouldShowRequestPermissionRationale(permission);
}

Revoked permission android.permission.CALL_PHONE

I'm trying to programmatically call to a number with following code:
String number = ("tel:" + numTxt.getText());
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse(number));
startActivity(intent);
I've set the permission in the Manifest:
<uses-permission android:name="android.permission.CALL_PHONE"/>
I'm working with real device for testing and debugging, it is Nexus 5 with Android M, my compileSdkVersion is 23. I'm getting the following Security Exception:
error: Permission Denial: starting Intent { act=android.intent.action.CALL dat=tel:xxxxxxxxxx cmp=com.android.server.telecom/.components.UserCallActivity } from ProcessRecord{cbbd7c1 5228:com.dialerTest.DialerApp/u0a96} (pid=5228, uid=10096) with revoked permission android.permission.CALL_PHONE
I've searched the web and this community for similar Q/A and couldn't find the answer. Any help will be appreciated.
Permission CALL_PHONE belong to dangerous permission group.
So if your apps target SDK is 23 or higher and your device is running on Android 6.0 or higher, you must request for CALL_PHONE permission while the app is running.
Example :
String number = ("tel:" + numTxt.getText());
mIntent = new Intent(Intent.ACTION_CALL);
mIntent.setData(Uri.parse(number));
// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(thisActivity,
Manifest.permission.CALL_PHONE)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(thisActivity,
new String[]{Manifest.permission.CALL_PHONE},
MY_PERMISSIONS_REQUEST_CALL_PHONE);
// MY_PERMISSIONS_REQUEST_CALL_PHONE is an
// app-defined int constant. The callback method gets the
// result of the request.
} else {
//You already have permission
try {
startActivity(mIntent);
} catch(SecurityException e) {
e.printStackTrace();
}
}
When your app requests permissions, the system presents a dialog box to the user. When the user responds, the system invokes your app's onRequestPermissionsResult() method, passing it the user response.
#Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_CALL_PHONE: {
// If request is cancelled, the result arrays are empty.
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission was granted, yay! Do the phone call
} else {
// permission denied, boo! Disable the
// functionality that depends on this permission.
}
return;
}
// other 'case' lines to check for other
// permissions this app might request
}
}
In android 6.0 (Api lvl 23) we have something called "Runtime Permissions". You have to read about it.
You can find documentation here.
You code could works only if you make an ACTION_DIAL, not an ACTION_CALL where you need to request a permission, so if you want to make a call, please follow this example:
MANIFEST:
<uses-permission android:name="android.permission.CALL_PHONE" />
Code:
import static android.Manifest.permission.CALL_PHONE;
Intent i = new Intent(Intent.ACTION_CALL);
i.setData(Uri.parse("tel:0612312312"));
/*
Intent i = new Intent(Intent.ACTION_DIAL);
i.setData(Uri.parse("tel:0612312312"));
if (i.resolveActivity(getPackageManager()) != null) {
startActivity(i);
}*/
if (ContextCompat.checkSelfPermission(getApplicationContext(), CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
startActivity(i);
} else {
requestPermissions(new String[]{CALL_PHONE}, 1);
}
in fragment class
Step 1:
import static android.Manifest.permission.CALL_PHONE;
step 2:Where your onclick button:
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:" +driver_no ));
if (ContextCompat.checkSelfPermission(getActivity(), CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
startActivity(callIntent);
} else {
requestPermissions(new String[]{CALL_PHONE}, 1);
}
[Or] you are using in activity class means change the getActivity to getApplicationContext()
FYI: If you're targeting Android 11, you need to add an Intent Query element for Intent.ACTION_DIAL in your manifest.
