由于本人学习Android也挺长时间了，一直把日记记在evernote里面，由于刚离职比较空闲就打算把evernote里的日志一遍遍整理出来发布到网上分享。
Android端的代码：
布局文件：activity_main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.example.androidusbserver.MainActivity" >
<EditText
android:id="@+id/etResult"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:inputType="textMultiLine"
>
</EditText>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<EditText
android:id="@+id/etInput"
android:layout_width="200dp"
android:layout_height="wrap_content">
</EditText>
<Button
android:id="@+id/btnSend"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Send" />
</LinearLayout>
</LinearLayout>
定义广播接收者接收adb发送的命令：AdbBroadcastReceiver.java
public class AdbBroadcastReceiver extends BroadcastReceiver {
private static final String TAG = "AdbBroadcastReceiver";
private static final String START_ACTION = "NotifyServiceStart";
private static final String STOP_ACTION = "NotifyServiceStop";
@Override
public void onReceive(Context context, Intent intent) {
String threadName = Thread.currentThread().getName();
String action = intent.getAction();
Log.d(TAG, threadName + "-->>"
+ "AdbBroadcastReceiver onReceive START_ACTION:" + action);
if (START_ACTION.equalsIgnoreCase(action)) {
context.startService(new Intent(context, NetWorkService.class));
