权限被拒绝无法获取位置 安卓.

Question

我在初始设置时向Android上的应用程序提供权限 跟踪地理位置和移动 LAC、手机 ID 和国家/地区代码以及塔代码。我在中途收到以下错误 - "权限被拒绝无法获取位置Android"，即最初在Android上安装应用程序时，它最初提供地理位置，但在中途它停止获取地理位置。

以上解决方案将不胜感激

请在下面找到代码 -

private void requestStoragePermission() {
Dexter.withActivity(this)
.withPermissions(
Manifest.permission.WAKE_LOCK,
Manifest.permission.READ_CONTACTS,
Manifest.permission.ACCESS_NETWORK_STATE,
Manifest.permission.ACCESS_WIFI_STATE,
Manifest.permission.READ_PHONE_STATE,
Manifest.permission.ACCESS_COARSE_LOCATION,
Manifest.permission.ACCESS_FINE_LOCATION)
.withListener(new MultiplePermissionsListener() {
@Override
public void onPermissionsChecked(MultiplePermissionsReport report) {
// check if all permissions are granted
if (report.areAllPermissionsGranted()) {
Toast.makeText(getApplicationContext(), "All permissions are granted!", Toast.LENGTH_SHORT).show();
}
// check for permanent denial of any permission
if (report.isAnyPermissionPermanentlyDenied()) {
// show alert dialog navigating to Settings
showSettingsDialog();
}
}
@Override
public void onPermissionRationaleShouldBeShown(List<PermissionRequest> permissions, PermissionToken token) {
token.continuePermissionRequest();
}
}).
withErrorListener(new PermissionRequestErrorListener() {
@Override
public void onError(DexterError error) {
Toast.makeText(getApplicationContext(), "Error occurred! ", Toast.LENGTH_SHORT).show();
}
})
.onSameThread()
.check();
}

Answer 1

获取位置数据，然后需要运行时权限尝试下面的代码。

将内容添加到您的应用程序中(如果不存在(，以及如何处理运行时权限。

尝试此操作，请确保您的应用级 gradle 文件在编译 sdk 版本中是最新的。

compileSdkVersion 27

然后在之后还将权限添加到 android 清单文件中。

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

并在检查运行时权限后，如下所示制作两种方法。

/** 
* this method check permission and return current state of permission need. 
*/ 
private boolean checkPermissions() { 
int permissionState = ActivityCompat.checkSelfPermission(this,
Manifest.permission.ACCESS_FINE_LOCATION); 
return permissionState == PackageManager.PERMISSION_GRANTED;
} 
/** 
* this method request to permission asked. 
*/ 
private void requestPermissions() { 
boolean shouldProvideRationale =
ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.ACCESS_FINE_LOCATION); 
if (shouldProvideRationale) {
Log.i(TAG, "Displaying permission rationale to provide additional context.");
} else { 
Log.i(TAG, "Requesting permission");
// previously and checked "Never ask again". 
ActivityCompat.requestPermissions(MainActivity.this,
new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
REQUEST_PERMISSIONS_REQUEST_CODE); 
}  
} 
/** 
* Callback received when a permissions request has been completed. 
*/ 
@Override 
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
@NonNull int[] grantResults) {
Log.i(TAG, "onRequestPermissionResult");
if (requestCode == REQUEST_PERMISSIONS_REQUEST_CODE) {
if (grantResults.length <= 0) {
// If user interaction was interrupted, the permission request is cancelled and you 
// receive empty arrays. 
Log.i(TAG, "User interaction was cancelled.");
} else if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// Permission was granted. Kick off the process of building and connecting 
// GoogleApiClient. 
buildGoogleApiClient(); 
} else { 
// Permission denied. 
} 
} 
} 

然后当调用获取位置方法时，然后像下面一样检查 在创建视图方法中

// Check if the user revoked runtime permissions.
if (!checkPermissions()) {
requestPermissions();
}
buildGoogleApiClient();
