Blocco in Marshmallow Fragment Activity per Maps

Question

Sto usando fragmentActivity per maps.In classe Java ottenere errore su setContentView. Il mio Mapscreen.java è come: Funziona bene su alcuni dispositivi che mostrano solo crash su marshmallow. O c'è qualche altra ragione?

public class MapScreen extends FragmentActivity implements LocationListener, 
GoogleApiClient.ConnectionCallbacks, 
GoogleApiClient.OnConnectionFailedListener { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.map_screen); 
    .... 

    SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager() 
      .findFragmentById(R.id.map); 
    googleMap = fm.getMap(); 
} 

    and my xml has fragment using SupportMapFragment as well. map_screen.xml is like : 


    <?xml version="1.0" encoding="utf-8"?> 
    <RelativeLayout 
     xmlns:android="http://schemas.android.com/apk/res/android" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:orientation="vertical" > 

     <fragment 
      android:id="@+id/map" 
      android:name="com.google.android.gms.maps.SupportMapFragment" 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent" 
      android:layout_alignParentLeft="true" 
      android:layout_alignParentTop="true" /> 

     <ImageView 
      android:id="@+id/startActivityButton" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_alignParentBottom="true" 
      android:layout_centerHorizontal="true" 
      android:layout_marginLeft="50dp" 
      android:layout_marginRight="50dp" 
      android:layout_marginBottom="44dp" 
      android:background="@drawable/end_meetup_btn" 
     /> 

    </RelativeLayout> 

io non sono in grado di trovare la stessa domanda Arrivare incidente qui a Marshmallow: "riga del file XML Binary # 7: Errore di gonfiaggio frammento di classe" Si prega di suggerire! Tentativo di trovare "Causato da: java.lang.NullPointerException: tentativo di richiamare il metodo virtuale 'booleano java.io.File.mkdir()' su un riferimento oggetto nullo" anche.

Answer 1

Il numero era su "Micro-max Android one mobile" che era 6.0 Marshmallow. questo dispositivo non ha abbastanza spazio di memoria interno o esterno. Anche non ha scheda SD.

Dopo aver seguito la risposta di George da questo:

NullPointerException from Google maps

ho installato la scheda di memoria ed ora incidente non è venuta.

Quindi ho trovato il problema è stato aggiornato servizi di Google Play che richiedono spazio (foto di Google aggiornato) che non era abbastanza nel mio dispositivo.

e anche uno della linea Error mostrava "causato da: java.lang.NullPointerException: tentativo di richiamare il metodo 'boolean java.io.File.mkdir()' virtuale su un riferimento oggetto nullo"

Ho deciso di controllare dopo aver installato la scheda SD. E ha funzionato

Answer 2

<!-- EXTERNAL_STORAGE permissions are optional for Android 6.0 onwards. --> 
    <uses-permission 
     android:name="android.permission.WRITE_EXTERNAL_STORAGE" 
     android:maxSdkVersion="22" /> 
    <uses-permission 
     android:name="android.permission.READ_EXTERNAL_STORAGE" 
     android:maxSdkVersion="22" /> 

Aggiungi questo al tuo manifest. Forse le mappe richiedono l'autorizzazione della sdcard per qualche altra cache in più o qualcosa del genere.

Answer 3

Questa è solo una soluzione che ho fatto. Se il controllo di sotto non riesce, invece di caricare la mappa, carico un frammento con un errore.

/** Checks if external storage is available for read and write */ 
public boolean isExternalStorageWritable() { 
    String state = Environment.getExternalStorageState(); 
    return Environment.MEDIA_MOUNTED.equals(state); 
} 

Answer 4

Aggiungere le autorizzazioni della scheda SD al file manifest.

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

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

Answer 5

Il problema è stato risolto nella versione 9.0.83 della raccolta di Google Play Services.
