Perm is a library that makes it simple to check and request Android Permissions at runtime (like Camera or GPS) for Apps targetting Android 6 or more.
Note that since version 1.1.1 of the library it is possible to request several Permissions at the same time.
Permissions can now also be checked from an Androidx Fragment.
To Check and Request permissions, simply create a Perm instance, and use isGranted(), areGranted(), isDenied(), areDenied(), or askPermissions() methods:
public class MainActivity extends AppCompatActivity {
private static final int PERMISSIONS_REQUEST = 1;
private static final String PERMISSIONS[] = {Manifest.permission.CAMERA, Manifest.permission.READ_CONTACTS};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
final Perm perm = new Perm(this, PERMISSIONS);
if (perm.areGranted()) {
Toast.makeText(this, "All Permissions granted", Toast.LENGTH_LONG).show();
} else {
perm.askPermissions(PERMISSIONS_REQUEST);
}
}
}To handle the result of the request, create a PermResult in the onRequestPermissionsResult of your Activity, and use isGranted(), areGranted(), isDenied(), areDenied(), or areCancelled() methods.
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == PERMISSIONS_REQUEST) {
PermResult permResult = new PermResult(permissions, grantResults);
if (permResult.areCancelled()) {
Toast.makeText(this, "Permission process cancelled", Toast.LENGTH_LONG).show();
} else {
for (String permission : PERMISSIONS) {
if (permResult.isGranted(permission)) {
Toast.makeText(this, permission + " granted", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(this, permission + " denied", Toast.LENGTH_SHORT).show();
}
}
}
}
}Don't forget to add the required permissions in your AndroidManifest.xml file! For example
<uses-permission
android:name="android.permission.CAMERA"
android:required="false" />
<uses-permission
android:name="android.permission.READ_CONTACTS" />Add the following maven{} line to your PROJECT build.gradle file
allprojects {
repositories {
jcenter()
maven { url "https://jitpack.io" } // add this line
}
}
Add the libary dependency to your APP build.gradle file
dependencies {
implementation 'com.github.smart-fun:Perm:1.2.0' // add this line
}
