一、创建 Service 远程服务
1、创建 Service
package kim.hsl.aidl_demo; import androidx.appcompat.app.AppCompatActivity; import android.content.ComponentName; import android.content.Context; import android.content.Intent; import android.content.ServiceConnection; import android.os.Bundle; import android.os.IBinder; import android.os.RemoteException; import android.util.Log; import android.view.View; import android.widget.Toast; import java.util.List; public class MainActivity extends AppCompatActivity { public static final String TAG = "MainActivity"; private IMyAidlInterface aidl; private ServiceConnection serviceConnection = new ServiceConnection() { /** * 传入需要的 Service , 让系统寻找指定的远程服务 * @param name * @param service */ @Override public void onServiceConnected(ComponentName name, IBinder service) { // 通过 IBinder 对象 , 从系统中获取对应的远程服务或代理对象 aidl = IMyAidlInterface.Stub.asInterface(service); Log.i(TAG, "AIDL 获取成功"); } @Override public void onServiceDisconnected(ComponentName name) { aidl = null; } }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // 通过 Action 和 包名 , 绑定远程服务 Intent intent = new Intent("android.intent.action.MyService"); intent.setPackage("kim.hsl.aidl_demo"); bindService(intent, serviceConnection, Context.BIND_AUTO_CREATE); findViewById(R.id.add).setOnClickListener((View view)->{ try { aidl.addStudent(new Student("Tom")); } catch (RemoteException e) { e.printStackTrace(); } }); findViewById(R.id.get).setOnClickListener((View view)->{ try { List<Student> students = aidl.getStudents(); Log.i(TAG, "students = " + students); } catch (RemoteException e) { e.printStackTrace(); } }); } }
2、AndroidManifest.xml 清单文件中配置 Service
<service android:name=".MyService" android:enabled="true" android:exported="true"> <intent-filter> <action android:name="android.intent.action.MyService" /> </intent-filter> </service>
二、绑定 Service 远程服务
1、核心代码
通过 Action 和 包名 , 绑定远程服务 , 其中 Action 是在 AndroidManifest.xml 清单文件中配置的 ;
// 通过 Action 和 包名 , 绑定远程服务 Intent intent = new Intent("android.intent.action.MyService"); intent.setPackage("kim.hsl.aidl_demo"); bindService(intent, serviceConnection, Context.BIND_AUTO_CREATE);
2、完整代码
完整代码如下 :
package kim.hsl.aidl_demo; import androidx.appcompat.app.AppCompatActivity; import android.content.ComponentName; import android.content.Context; import android.content.Intent; import android.content.ServiceConnection; import android.os.Bundle; import android.os.IBinder; import android.os.RemoteException; import android.util.Log; import android.view.View; import android.widget.Toast; import java.util.List; public class MainActivity extends AppCompatActivity { public static final String TAG = "MainActivity"; private IMyAidlInterface aidl; private ServiceConnection serviceConnection = new ServiceConnection() { /** * 传入需要的 Service , 让系统寻找指定的远程服务 * @param name * @param service */ @Override public void onServiceConnected(ComponentName name, IBinder service) { // 通过 IBinder 对象 , 从系统中获取对应的远程服务或代理对象 aidl = IMyAidlInterface.Stub.asInterface(service); Log.i(TAG, "AIDL 获取成功"); } @Override public void onServiceDisconnected(ComponentName name) { aidl = null; } }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // 通过 Action 和 包名 , 绑定远程服务 Intent intent = new Intent("android.intent.action.MyService"); intent.setPackage("kim.hsl.aidl_demo"); bindService(intent, serviceConnection, Context.BIND_AUTO_CREATE); findViewById(R.id.add).setOnClickListener((View view)->{ try { aidl.addStudent(new Student("Tom")); } catch (RemoteException e) { e.printStackTrace(); } }); findViewById(R.id.get).setOnClickListener((View view)->{ try { List<Student> students = aidl.getStudents(); Log.i(TAG, "students = " + students); } catch (RemoteException e) { e.printStackTrace(); } }); } }
3、运行结果
点击添加按钮 , 即可向远程服务中添加 Student 对象 , 点击获取按钮 , 即可在日志中打印之前添加的所有 Student 对象 ;
