hi you can use these permissions in the manifest file with a different permission,
<uses-feature android:name="android.hardware.camera.any" android:required="true" /> <uses-feature android:name="android.hardware.camera.autofocus" android:required="false" />
If it still doesn't work, you are probably using android M, so you need to add permissions programmatically.
here is an example
hi here are a few steps for permission to install for android M and remember that you must declare the same permission in the manifest file.
Step 1. Declare a 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\ 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 a 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 action
@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 the oncreate method,
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { checkMultiplePermissions(REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS, MyActivity.this); } else {
Step 4. Dialog to deny permissions
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 activities where you 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 any permission you can call from here, and every result that you can get in the onRequestPermissionsResult override method, is this.
Thankyou
hope this helps you (Y).
