Denial autorizzazione: fornitore di apertura com.android.providers.contacts.ContactsProvider2

Question

Sono nuovo di Android e ho creato un'applicazione da zero utilizzando Android Studio e il modello LoginActivity. Ho scelto come target SDK 23 e la versione minimo è 15. Android Studio generato il seguente manifesto:

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.uprope.uprope" > 

    <!-- To auto-complete the email text field in the login form with the user's emails --> 
    <uses-permission android:name="android.permission.GET_ACCOUNTS" /> 
    <uses-permission android:name="android.permission.READ_PROFILE" /> 
    <uses-permission android:name="android.permission.READ_CONTACTS" /> 
    <application 
     android:allowBackup="true" 
     android:icon="@mipmap/ic_launcher" 
     android:label="@string/app_name" 
     android:theme="@style/AppTheme" > 
     <activity 
      android:name=".LoginActivity" 
      android:label="@string/app_name" 
      android:windowSoftInputMode="adjustResize|stateVisible" > 
     </activity> 
    </application> 

</manifest> 

Quando provo a fare funzionare il modello vuoto, ottengo questo stack trace:

Cosa sta causando questa eccezione?

Answer 1

Api 23 ha alcuni miglioramenti di sicurezza (e significa alcuni bug per lo sviluppo). Sono sicuro che hai definito targetSdkVersion="23". Se si modifica a 22, sarà funziona bene, controllare

Answer 2

Se si sta testando su M Android è necessario chiedere all'utente il permesso di leggere i contatti in fase di esecuzione in questo modo:

private void accessContacts(){ 
    if (!mayRequestContacts()) { 
     return; 
    } 
    // This Build is < 6 , you can Access contacts here. 
} 

Chiedete per un permesso del genere:

private boolean mayRequestContacts() { 
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) { 
     return true; 
    } 
    if (checkSelfPermission(READ_CONTACTS) == PackageManager.PERMISSION_GRANTED) { 
     return true; 
    } 
    if (shouldShowRequestPermissionRationale(READ_CONTACTS)) { 
     Snackbar.make(mEmailView, R.string.permission_rationale, Snackbar.LENGTH_INDEFINITE) 
       .setAction(android.R.string.ok, new View.OnClickListener() { 
        @Override 
        @TargetApi(Build.VERSION_CODES.M) 
        public void onClick(View v) { 
         requestPermissions(new String[]{READ_CONTACTS}, REQUEST_READ_CONTACTS); 
        } 
       }); 
    } else { 
     requestPermissions(new String[]{READ_CONTACTS}, REQUEST_READ_CONTACTS); 
    } 
    return false; 
} 

poi sovrascrivere onRequestPermissionsResult

@Override 
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, 
             @NonNull int[] grantResults) { 
    if (requestCode == REQUEST_READ_CONTACTS) { 
     if (grantResults.length == 1 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 
      // Permission granted , Access contacts here or do whatever you need. 
     } 
    } 
} 

Aggiungere questo ai vostri importazioni:

 import static android.Manifest.permission.READ_CONTACTS; 

e definire un intero come un ID per l'identità READ_CONTACTS richiesta di autorizzazione.

 private static final int REQUEST_READ_CONTACTS = 0; 

spero che questo ha aiutato.
