hi you can use these permission in your manifest file with other permission,
<uses-feature
android:name="android.hardware.camera.any"
android:required="true" />
<uses-feature
android:name="android.hardware.camera.autofocus"
android:required="false" />
If still it not working then may be you are using android M,SO you need to programmatically add permissions.
here is example
hi here is few steps for setup permission for android M and remember you should declare same permission in manifest file as well.
Step 1. Declare global variable :
public final int REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS = 1;
//requests for runtime time permissions
String CAMERA_PERMISSION = android.Manifest.permission.CAMERA;
String READ_EXTERNAL_STORAGE_PERMISSION = android.Manifest.permission.READ_EXTERNAL_STORAGE;
String WRITE_EXTERNAL_STORAGE_PERMISSION = android.Manifest.permission.WRITE_EXTERNAL_STORAGE;
// for security permissions
@DialogType
private int mDialogType;
private String mRequestPermissions = "We are requesting the camera and Gallery permission as it is absolutely necessary for the app to perform it\'s functionality.\nPlease select \"Grant Permission\" to try again and \"Cancel \" to exit the application.";
private String mRequsetSettings = "You have rejected the camera and Gallery permission for the application. As it is absolutely necessary for the app to perform you need to enable it in the settings of your device.\nPlease select \"Go to settings\" to go to application settings in your device and \"Cancel \" to exit the application.";
private String mGrantPermissions = "Grant Permissions";
private String mCancel = "Cancel";
private String mGoToSettings = "Go To Settings";
private String mPermissionRejectWarning = "Cannot Proceed Without Permissions</string>
<string name="explanation_permission_location_request">We are requesting the location permission as it is necessary for the app to perform search functionality properly.\nPlease select \"Grant Permission\" to try again and \"Cancel \" to deny permission.";
// create dialog like this.
// type of dialog opened in MainActivity
@IntDef({DialogType.DIALOG_DENY, DialogType.DIALOG_NEVER_ASK})
@Retention(RetentionPolicy.SOURCE)
@interface DialogType {
int DIALOG_DENY = 0, DIALOG_NEVER_ASK = 1;
}
Step 2. Use this code in your main activity
@TargetApi(Build.VERSION_CODES.M)
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
switch (requestCode) {
case REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS:
if (grantResults[0] == PackageManager.PERMISSION_GRANTED && grantResults[1] == PackageManager.PERMISSION_GRANTED && grantResults[2] == PackageManager.PERMISSION_GRANTED) {
// Call your camera here.
} else {
boolean showRationale1 = shouldShowRequestPermissionRationale(CAMERA_PERMISSION);
boolean showRationale2 = shouldShowRequestPermissionRationale(READ_EXTERNAL_STORAGE_PERMISSION);
boolean showRationale3 = shouldShowRequestPermissionRationale(WRITE_EXTERNAL_STORAGE_PERMISSION);
if (showRationale1 && showRationale2 && showRationale3) {
//explain to user why we need the permissions
mDialogType = ValueConstants.DialogType.DIALOG_DENY;
// Show dialog with
openAlertDialog(mRequestPermissions, mGrantPermissions, mCancel, this, MyActivity.this);
} else {
//explain to user why we need the permissions and ask him to go to settings to enable it
mDialogType = ValueConstants.DialogType.DIALOG_NEVER_ASK;
openAlertDialog(mRequsetSettings, mGoToSettings, mCancel, this, MyActivity.this);
}
}
break;
default:
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
//check for camera and storage access permissions
@TargetApi(Build.VERSION_CODES.M)
private void checkMultiplePermissions(int permissionCode, Context context) {
String[] PERMISSIONS = {CAMERA_PERMISSION, READ_EXTERNAL_STORAGE_PERMISSION, WRITE_EXTERNAL_STORAGE_PERMISSION};
if (!hasPermissions(context, PERMISSIONS)) {
ActivityCompat.requestPermissions((Activity) context, PERMISSIONS, permissionCode);
} else {
// Open your camera here.
}
}
private boolean hasPermissions(Context context, String... permissions) {
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
for (String permission : permissions) {
if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
return false;
}
}
}
return true;
}
Step 3. Call this method in your oncreate method,
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
checkMultiplePermissions(REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS, MyActivity.this);
} else {
// Open your camera here.
}
Step 4. Dialog for permission deny
public static void openAlertDialog(String message, String positiveBtnText, String negativeBtnText,
final OnDialogButtonClickListener listener,Context mContext) {
AlertDialog.Builder builder = new AlertDialog.Builder(mContext, R.style.AlertDialogCustom);
builder.setPositiveButton(positiveBtnText, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
listener.onPositiveButtonClicked();
}
});
builder.setPositiveButton(positiveBtnText, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
listener.onNegativeButtonClicked();
}
});
builder.setTitle(mContext.getResources().getString(R.string.app_name));
builder.setMessage(message);
builder.setIcon(android.R.drawable.ic_dialog_alert);
builder.setCancelable(false);
builder.create().show();
}
// Create this interface
public interface OnDialogButtonClickListener {
void onPositiveButtonClicked();
void onNegativeButtonClicked();
}
and implement this in your activity where need to add permissions.
@Override
public void onPositiveButtonClicked() {
switch (mDialogType) {
case ValueConstants.DialogType.DIALOG_DENY:
checkMultiplePermissions(REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS, MyActivity.this);
break;
case ValueConstants.DialogType.DIALOG_NEVER_ASK:
redirectToAppSettings(MyActivity.this);
break;
}
}
@Override
public void onNegativeButtonClicked() {
}
And anyone permission you can call from here and every result you can get in override method onRequestPermissionsResult this one.
UPDATE :
Now we have very sorted way for permission handling. So,here is the steps. I have added here for kotlin.
Step 1. Declare this as global variable or any where.
private val permissions = registerForActivityResult(ActivityResultContracts.RequestMultiplePermissions()) { granted ->
granted.entries.forEach {
when (it.value) {
true -> {
// Call whatever you want to do when someone allow the permission.
}
false -> {
showPermissionSettingsAlert(requireContext())
}
}
}
}
Step 2.
// You can put this line in constant.
val storagePermission = arrayOf(
Manifest.permission.READ_EXTERNAL_STORAGE
)
// You can put this in AppUtil.
fun checkPermissionStorage(context: Context): Boolean {
val result =
ContextCompat.checkSelfPermission(context, Manifest.permission.READ_EXTERNAL_STORAGE)
return result == PackageManager.PERMISSION_GRANTED
}
// Put this where you need Permission check.
if (!checkPermissionStorage(requireContext())) {
permissions.launch(
storagePermission
)
} else {
// Permission is already added.
}
Step 3. Permission rejection Dialog. If you want you can use this.
fun showPermissionSettingsAlert(context: Context) {
val builder = AlertDialog.Builder(context)
builder.setTitle("Grant Permission")
builder.setMessage("You have rejected the Storage permission for the application. As it is absolutely necessary for the app to perform you need to enable it in the settings of your device. Please select \"Go to settings\" to go to application settings in your device.")
builder.setPositiveButton("Allow") { dialog, which ->
val intent = Intent()
intent.action = Settings.ACTION_APPLICATION_DETAILS_SETTINGS
val uri = Uri.fromParts("package", context.packageName, null)
intent.data = uri
context.startActivity(intent)
}
builder.setNeutralButton("Deny") { dialog, which ->
dialog.dismiss()
}
val dialog = builder.create()
dialog.show()
}
Thankyou
hope this will help you (Y).
