Googleマップはアンドロイドでは表示されませんmarshmallow（6.0）？

Question

私はアプリを開発しています、ここで私はGoogleマップを使用しています。 Googleマップは現在の場所を他の端末に表示しますが、現在の位置は表示されません（6.0）。

marshmallow（6.0）では、アプリを開くとマップが表示されますが、現在の位置は表示されません。

私はアプリを開くと、現在の場所を表示する必要がありますすべてのデバイスでGoogleマップの現在の場所を表示する。

どうすればよいですか？

Answer 1

あなたtargetSDKが23である場合は、実行時に場所許可を確認する必要があります。デフォルトでは許可されていません。あなたが許可を要求するためにこのような何かを行う必要がありますあなたの場合は

：次に

int hasLocationPermission = checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION); 
    if (hasLocationPermission != PackageManager.PERMISSION_GRANTED) { 
     requestPermissions(new String[] {Manifest.permission.ACCESS_FINE_LOCATION}, 
       REQUEST_CODE_ASK_PERMISSIONS); 
    } 

結果はチェックと要求許可のこの偉大なチュートリアルを読んでください詳細については

@Override 
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {} 

で返されますAndroid 6.0の場合New Android Runtime permission

Answer 2

実行時のアクセス許可でこれを試すことができます：

 public void checkPermission() { 
    if (ContextCompat.checkSelfPermission(YourActivity.this, 
      Manifest.permission.ACCESS_FINE_LOCATION) 
      != PackageManager.PERMISSION_GRANTED) { 

     // Should we show an explanation? 
     if (ActivityCompat.shouldShowRequestPermissionRationale(YourActivity.this, 
       Manifest.permission.ACCESS_FINE_LOCATION)) { 

      // Show an expanation to the user *asynchronously* -- don't block 
      // this thread waiting for the user's response! After the user 
      // sees the explanation, try again to request the permission. 

     } 
} 

Answer 3

Android 6.0以降では、実行時にアクセス許可をチェックする必要があると思います。以下は、実行時にパーミッションをチェックするためのスニペットです。

PackageManager pm = getApplicationContext().getPackageManager(); 
int hasCoarseLocPerm = pm.checkPermission(Manifest.permission.ACCESS_COARSE_LOCATION,getApplicationContext().getPackageName()); 
int hasFineLocPerm = pm.checkPermission(Manifest.permission.ACCESS_FINE_LOCATION,getApplicationContext().getPackageName()); 
if (!(hasCoarseLocPerm == PackageManager.PERMISSION_GRANTED&&hasFineLocPerm == PackageManager.PERMISSION_GRANTED)) { 
      // do stuff 
      Toast.makeText(PreferencesActivity.this, "Please provide all the permissions required", Toast.LENGTH_LONG).show(); 
} 

Answer 4

注：marashmallowまたは上記これらの権限で実行時間を与え、許可がmainfest

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

ランタイム

public static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 10; 

private String[] permissions= new String[]{ 
       Manifest.permission.ACCESS_COARSE_LOCATION, 
    Manifest.permission.ACCESS_FINE_LOCATION}; 


if (checkPermissions()) 
     // permissions granted.  
} 

private boolean checkPermissions() { 
    int result; 
    List<String> listPermissionsNeeded = new ArrayList<>(); 
    for (String p:permissions) { 
     result = ContextCompat.checkSelfPermission(this,p); 
     if (result != PackageManager.PERMISSION_GRANTED) { 
      listPermissionsNeeded.add(p); 
     } 
    } 
    if (!listPermissionsNeeded.isEmpty()) { 
     ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]),REQUEST_ID_MULTIPLE_PERMISSIONS); 
     return false; 
    } 
    return true; 
}

Answer 5

Android Mを実行していますか？その場合は、マニフェストにpermissionsを宣言するだけでは不十分であるためです。一部のアクセス許可については、ユーザーに明示的にユーザーに問い合わせる必要があります。run-time：

実行時のアクセス許可はLinkにチェックしてください。

コードスニペット

この世界を定義します。

private static final int PERMISSION_REQUEST_CODE = 1; 

そして、この意志のonCreateになります。

if (ContextCompat.checkSelfPermission(Maps_Activity.this, 
     Manifest.permission.ACCESS_FINE_LOCATION) 
     != PackageManager.PERMISSION_GRANTED) { 

    // Should we show an explanation? 
    if (ActivityCompat.shouldShowRequestPermissionRationale(Maps_Activity.this, 
      Manifest.permission.ACCESS_FINE_LOCATION)) { 

     // Show an expanation to the user *asynchronously* -- don't block 
     // this thread waiting for the user's response! After the user 
     // sees the explanation, try again to request the permission. 

    } else { 

     // No explanation needed, we can request the permission. 

     ActivityCompat.requestPermissions(Maps_Activity.this, 
       new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 
       PERMISSION_REQUEST_CODE); 

     // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an 
     // app-defined int constant. The callback method gets the 
     // result of the request. 
    } 
} 

と書き換えてonRequestPermissionsResult。

@Override 
public void onRequestPermissionsResult(int requestCode, 
             String permissions[], int[] grantResults) { 
    switch (requestCode) { 
     case PERMISSION_REQUEST_CODE: { 
      // If request is cancelled, the result arrays are empty. 
      if (grantResults.length > 0 
        && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 

       // permission was granted, yay! 

      } else { 

       // permission denied, boo! Disable the 
       // functionality that depends on this permission. 
      } 
      return; 
     } 

     // other 'case' lines to check for other 
     // permissions this app might request 
    } 
}
