java.lang.NumberFormatException：無効なint： "android.permission.ACCESS_COARSE_LOCATION"

Question

私のアプリでGoogleマップを実装していて、MapsActivityで以下のエラーが発生してアプリがクラッシュしました。

OnMapReady（）メソッドでエラーが発生します。 MapReadyでは、ユーザーがアプリ内からロケーションサービスをオンにするように表示するdisplaySettingsRequestを呼び出しました。あなたがしようとしている

public class MapsActivity extends BaseActivity implements OnMapReadyCallback, ConnectionCallbacks, OnConnectionFailedListener {  
private void displayLocationSettingsRequest(Context context) { 
    GoogleApiClient googleApiClient = new GoogleApiClient.Builder(context) 

    PendingResult<LocationSettingsResult> result = LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build()); 
    result.setResultCallback(result1 -> { 
     final Status status = result1.getStatus(); 
     switch (status.getStatusCode()) { 
      case LocationSettingsStatusCodes.SUCCESS: 
       Log.i(TAG, "All location settings are satisfied."); 
       break; 
      case LocationSettingsStatusCodes.RESOLUTION_REQUIRED: 
       Log.i(TAG, "Location settings are not satisfied. Show the user a dialog to upgrade location settings "); 

       try { 
        // Show the dialog by calling startResolutionForResult(), and check the result 
        // in onActivityResult(). 
        status.startResolutionForResult(MapsActivity.this, HawkConstants.REQUEST_CODE); 
       } catch (IntentSender.SendIntentException e) { 
        Log.i(TAG, "PendingIntent unable to execute request."); 
       } 
       break; 
      case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE: 
       Log.i(TAG, "Location settings are inadequate, and cannot be fixed here. Dialog not created."); 
       break; 
     } 
    }); 
} 

@Override 
public void onMapReady(GoogleMap googleMap) { 
    displayLocationSettingsRequest(App.getContext()); 
    mMap = googleMap; 
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {    
     return; 
    } 
    mMap.setMyLocationEnabled(true); 

} 

@Override 
public void onConnected(@Nullable Bundle bundle) { 
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {   
     ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.ACCESS_COARSE_LOCATION}, 
       Integer.parseInt(Manifest.permission.ACCESS_COARSE_LOCATION)); 
     return; 
    } 
    mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
      mGoogleApiClient); 
} 

Answer 1

：

マップのアクティビティ

Integer.parseInt(Manifest.permission.ACCESS_COARSE_LOCATION)); 

しかしManifest.permission.ACCESS_COARSE_LOCATIONは十進法の数値のString表現ではありません。それはNumberFormatExceptionを引き起こします。

StackTraceによると、Manifest.permission.ACCESS_COARSE_LOCATIONは“android.permission.ACCESS_COARSE_LOCATION”です。 Stringは"10"、"1234123"、"-11121"のようにしか解析できませんが、Javaは数字に"java cute string"を解析しません。
