Ausnahme- Schreiben Ausnahme für Paket

Question

Dies ist eine kleine Aufgabe zum Einfügen von einfachen Textdaten in SQLite-Datenbank. Ich habe die SQLiteOpenHelper-Klasse dafür verwendet und den angegebenen Code verwendet. Ich habe hier einige ähnliche Fragen gefunden, aber nicht die gleichen. Bitte hilf mir. Hier ist die Ausnahme-

ich in meiner AndroidManifest.xml Datei folgenden Berechtigungen verwendet haben:

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

das ist mein DBHelper klassen

public class DBHelper extends SQLiteOpenHelper { 

public static final String DATABASE_NAME = "CANDIDATES"; 
public static final String TABLE_NAME = "CANDIDATES_TABLE"; 
public static final String NAME = "NAME"; 
public static final String AGE = "AGE"; 
public static final String QUAL = "QUALIFICATION"; 
public static final String SALARY = "SALARY"; 
public static final String ADD = "ADDRESS"; 
public static final String DES = "DESCRIPTION"; 
Context context; 


public DBHelper(Context context) { 
    super(context, DATABASE_NAME, null, 1); 
    this.context=context; 
} 

@Override 
public void onCreate(SQLiteDatabase db) { 
    db.execSQL("create table "+ TABLE_NAME +" ("+NAME+" TEXT,"+AGE+" INTEGER,"+QUAL+" TEXT,"+SALARY+" INTEGER,"+ADD+" TEXT,"+DES+" TEXT)"); 

} 

public boolean insertData(String name,int age,String qual,int salary, String add, String des){ 
    SQLiteDatabase db=this.getWritableDatabase(); 
    ContentValues contentValues=new ContentValues(); 
    contentValues.put(NAME,name); 
    contentValues.put(AGE,age); 
    contentValues.put(QUAL,qual); 
    contentValues.put(SALARY,salary); 
    contentValues.put(ADD,add); 
    contentValues.put(DES,des); 
    long result=db.insert(TABLE_NAME,null,contentValues); 
    Log.v("check",name+age+""+qual+salary+""+add+des); 
    if(result==-1){ 
     return false; 
    } 
    else return true; 
} 

public Cursor getData(){ 
    SQLiteDatabase db=this.getWritableDatabase(); 
    Cursor cursor=db.rawQuery("Select * from"+TABLE_NAME,null); 
    return cursor; 
} 
@Override 
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
    db.execSQL("DROP TABLE IF EXISTS "+TABLE_NAME); 
    onCreate(db); 
} 

}

Answer 1

Sie müssen runtime permissions. Hinzufügen Manifest fragen für neuere nicht genügend Versionen ist.

if (ContextCompat.checkSelfPermission(thisActivity, 
      Manifest.permission.READ_CONTACTS) 
    != PackageManager.PERMISSION_GRANTED) { 

// Should we show an explanation? 
if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity, 
     Manifest.permission.READ_CONTACTS)) { 

    // Show an explanation 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(thisActivity, 
      new String[]{Manifest.permission.READ_CONTACTS}, 
      MY_PERMISSIONS_REQUEST_READ_CONTACTS); 

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

Sie müssen diese Zeile zu Ihrem Manifest hinzufügen:

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