Android 源码编译AIDL 使用实例讲解及Android Studio AIDL的调用详解_系统应用编译 aidl

package com.asus.cnfindphone.service.persistentdata;
 
// Declare any non-default types here with import statements
 
interface IDataBlockService {
    byte[] read();
    int write(in byte[] data);
    void wipe();
}

2. 创建AIDL Service实现类

package com.asus.cnfindphone.service.persistentdata;
 
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;
import android.os.RemoteException;
import android.util.Log;
 
import android.service.persistentdata.PersistentDataBlockManager;
 
/**
 * Created by Qinghua_Liu on 2017-2-28.
 */
public class DataBlockService extends Service {
    private static String TAG = "Qinghua";
 
    @Override
    public void onCreate() {
        super.onCreate();
    }
 
    private boolean bInPSTList(String calling) {
        boolean bRes = false;
        if (calling.equalsIgnoreCase("asus.findmyphone")) {
            bRes = true;
        }
        Log.d(TAG, "bInPSTList==" + bRes);
        return bRes;
    }
 
    @Override
    public IBinder onBind(Intent intent) {
        //String callingApp = intent.getComponent().getPackageName();
        return mBind;
    }
 
    private final IDataBlockService.Stub mBind = new IDataBlockService.Stub() {
        @Override
        public byte[] read() throws RemoteException {
            byte[] bytes = null;
            Log.d(TAG, "DataBlockService.read()");
            String callingApp = getApplicationContext().getPackageManager().getNameForUid(Binder.getCallingUid());
            Log.d(TAG, "callingApp==" + callingApp);
            if (bInPSTList(callingApp)) {
                PersistentDataBlockManager pdbManager = (PersistentDataBlockManager) getApplicationContext().getSystemService(Context.PERSISTENT_DATA_BLOCK_SERVICE);
                bytes = pdbManager.read();
                //String id ="shenshiid";
                //return id.getBytes();
            }
            Log.d(TAG, "pdbManager.read()==" + new String(bytes));
            return bytes;
        }
 
        @Override
        public int write(byte[] data) throws RemoteException {
            Log.d(TAG, "DataBlockService.write()" + new String(data));
            String callingApp = getApplicationContext().getPackageManager().getNameForUid(Binder.getCallingUid());
            Log.d(TAG, "callingApp==" + callingApp);
            if (bInPSTList(callingApp)) {
                if (data != null && data.length > 0) {
                    PersistentDataBlockManager pdbManager = (PersistentDataBlockManager) getApplicationContext().getSystemService(Context.PERSISTENT_DATA_BLOCK_SERVICE);
                    pdbManager.write(data);
                }
            }
            return 0;
        }
 
        @Override
        public void wipe() throws RemoteException {
 
        }
    };
}

3.Manifest 静态注册Service

4. 过滤Service 调用者package：

@Override
        public byte[] read() throws RemoteException {
            byte[] bytes = null;
            Log.d(TAG, "DataBlockService.read()");
            String callingApp = getApplicationContext().getPackageManager().getNameForUid(Binder.getCallingUid());
            Log.d(TAG, "callingApp==" + callingApp);
            if (bInPSTList(callingApp)) {
                PersistentDataBlockManager pdbManager = (PersistentDataBlockManager) getApplicationContext().getSystemService(Context.PERSISTENT_DATA_BLOCK_SERVICE);
                bytes = pdbManager.read();
                //String id ="shenshiid";
                //return id.getBytes();
            }
            Log.d(TAG, "pdbManager.read()==" + new String(bytes));
            return bytes;
        }

private boolean bInPSTList(String calling) {
        boolean bRes = false;
        if (calling.equalsIgnoreCase("asus.findmyphone")) {
            bRes = true;
        }
        Log.d(TAG, "bInPSTList==" + bRes);
        return bRes;
    }

            }

}
@Override protected void onDestroy() 
{ 

super.onDestroy(); 
unbindService(conn); 
dataBlockService = null; 
}
