问题描述
我要检查API 23+是否已授予SMS读取许可.因此,我将其实现如下;
I want to check SMS reading permission is Granted or not in API 23+. So I implemented its as follows;
if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_SMS) != PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_SMS}, PERMISSIONS_REQUEST_READ_SMS);
}
处理许可响应.如下;
Handling permission resp. as follows;
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
if (requestCode == PERMISSIONS_REQUEST_READ_SMS) {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//Doing task regarding SMS permission.
}else if (grantResults[0] == PackageManager.PERMISSION_DENIED){
if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.READ_SMS)) {
//Show an explanation to the user *asynchronously*
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("This permission is important to Read SMS.")
.setTitle("Important permission required");
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
ActivityCompat.requestPermissions(GenerateOTPActivity.this, new String[]{Manifest.permission.READ_SMS}, PERMISSIONS_REQUEST_READ_SMS);
}
});
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_SMS}, PERMISSIONS_REQUEST_READ_SMS);
}else{
//Never ask again and handle your app without permission.
}
}
}
}
默认情况下,系统会授予SMS权限,因此checkSelfPermission()会返回零,但是当我手动拒绝设备设置的权限时,checkSelfPermission()也会返回零值.
By default SMS permission is Granted so checkSelfPermission() reterns zero but when I manually deny permission from device setting then also checkSelfPermission() returns zero value.
我不知道如何检查SMS许可是否被拒绝.请提供一些解决方案.
I dont understand how to check SMS permission is denied or not. Please provide me some solutions.

尝试此代码,并在android清单中提供权限
try this codes and also provide permissions in android manifest
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
marshmallowPermission(); //***** marshmaloow runtime permission*****//
}
public Boolean marshmallowPermission(){
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (checkPermission()) {
Toast.makeText(this,"Permission already granted.", Toast.LENGTH_SHORT).show();
} else {
requestPermission();
}
}
return true;
}
@TargetApi(Build.VERSION_CODES.M)
public boolean checkPermission(){
int sms = checkSelfPermission(android.Manifest.permission.READ_SMS);
if (sms == PackageManager.PERMISSION_GRANTED ){
return true;
} else {
return false;
}
}
@TargetApi(Build.VERSION_CODES.M)
public void requestPermission(){
if (shouldShowRequestPermissionRationale(android.Manifest.permission.READ_SMS)){
if(shouldShowRequestPermissionRationale(android.Manifest.permission.READ_SMS)){
Toast.makeText(this,"sms Permission must be needed which allows to access sms . Please allow sms in App Settings for additional functionality.",Toast.LENGTH_LONG).show();
}
Intent intent = new Intent();
intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
Uri uri = Uri.fromParts("package", this.getPackageName(), null);
intent.setData(uri);
this.startActivity(intent);
} else {
requestPermissions(new String[]{android.Manifest.permission.READ_SMS},100);
}
}
@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case 100:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(this,"Permission Granted, Now you can access app without bug.",Toast.LENGTH_LONG).show();
} else {
Toast.makeText(this,"Permission Denied, App maybe get crashed.", Toast.LENGTH_LONG).show();
}
break;
}
}
