Denial di autorizzazione durante il tentativo di accesso ai contatti in Android

Question

Sto tentando di accedere ai contatti sul dispositivo e successivamente visualizzarli in un elenco, tuttavia quando provo ad accedervi con un cursore, viene visualizzato un errore che mi manca autorizzazioni per READ_CONTACTS ma ho già dato i permessi nel mio AndroidManifest.xml

codice in cui accedo a contatto:

public void setupCursor() { 
    Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null); 

    while (cursor.moveToNext()) { 
     String name = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); 
     String number = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
     Toast.makeText(this, name + ": " + number, Toast.LENGTH_SHORT).show(); 
    } 
    cursor.close(); 
} 

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="io.github.brady131313.textback" > 

<uses-sdk android:minSdkVersion="15" android:targetSdkVersion="21"/> 

<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=".ActivityMainSettings" 
     android:label="@string/app_name" > 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 

    <activity 
     android:name=".ActivityContactSelect" 
     android:label="Select Contacts"> 
    </activity> 

</application> 


</manifest>

Answer 1

Aggiungere l'autorizzazione di utilizzo al di fuori del tag dell'applicazione e rendere android.permission in lettere minuscole. che dovrebbe risolvere il problema come concordato sotto nei commenti

Answer 2

Dato che il nuovo runtime permission model viene introdotto in Android 6.0,

Spero che questo codice sarà utile se si desidera utilizzare runtime permission model. Puoi anche vedere l'implementazione dei dettagli e ottenere il codice sorgente da here.

    private ListView lstNames;

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

     // Find the list view 
     this.lstNames = (ListView) findViewById(R.id.lstNames); 

     // Read and show the contacts 
     showContacts(); 
    }

      //After this point you wait for callback in onRequestPermissionsResult(int, String[], int[]) overriden method 
     } else { 
      // Android version is lesser than 6.0 or the permission is already granted.

    }

     List<String> contacts = new ArrayList<>();

     ContentResolver cr = getContentResolver(); 
     // Get the Cursor of all the contacts 
     Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); 

     // Move the cursor to first. Also check whether the cursor is empty or not. 
     if (cursor.moveToFirst()) { 
      // Iterate through the cursor 
      do {

       String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 
       contacts.add(name);

     } 
     // Close the curosor 
     cursor.close(); 

     return contacts; 
    } 
} 

Answer 3

che avevo stessa situazione come quello che si ha, in pratica è solo bisogno di cambiare "android.permission.READ_CONTACTS" in minuscolo per il primo semestre si il permesso.
