让LED47R5200开机自动播放电视

说明

　　家里买了个康佳的LED47R5200PDE的Android电视，反应各种慢，操作各种不流畅。太郁闷了，感觉完全是被康佳和京东给坑了。打电话各种反应，结果是各种不理睬。特别是康佳，严重鄙视之。最让人讨厌的是每次开机都要进入Android主页，而不是直接播放电视。心中那个郁闷啊。这让开机时需要两个遥控器操作。

　　算了，求人不如求己，我自己写个开机自动播放电视的应用。

反编译分析

2013-12-15更新，下载地址在文件最后，

话不多说，下面开始。

==========================================================================================================

下载一个launch，反编译之。

1、首先查看AndroidManifest.xml文件，找到

       <activity android:theme="@style/Theme" android:name="com.cyanogenmod.trebuchet.Launcher" android:clearTaskOnLaunch="true" android:stateNotNeeded="true" android:launchMode="singleTask" android:windowSoftInputMode="adjustPan">            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.HOME" />                <category android:name="android.intent.category.DEFAULT" />                <category android:name="android.intent.category.MONKEY" />            </intent-filter>        </activity>

2、使用UltraEdit查看com.cyanogenmod.trebuchet.Launcher的代码（Launcher.smali），呼出函数列表，找到：

.method private startTVSystem()V    .locals 7    .prologue    .line 884    const-string v4, "activity"    invoke-virtual {p0, v4}, Lcom/cyanogenmod/trebuchet/Launcher;->getSystemService(Ljava/lang/String;)Ljava/lang/Object;    move-result-object v0    check-cast v0, Landroid/app/ActivityManager;    .line 885    .local v0, am:Landroid/app/ActivityManager;    const/4 v4, 0x2    invoke-virtual {v0, v4}, Landroid/app/ActivityManager;->getRunningTasks(I)Ljava/util/List;    move-result-object v4    const/4 v5, 0x0    invoke-interface {v4, v5}, Ljava/util/List;->get(I)Ljava/lang/Object;    move-result-object v4    check-cast v4, Landroid/app/ActivityManager$RunningTaskInfo;    iget-object v1, v4, Landroid/app/ActivityManager$RunningTaskInfo;->topActivity:Landroid/content/ComponentName;    .line 886    .local v1, cn:Landroid/content/ComponentName;    const-string v4, "Launcher"    new-instance v5, Ljava/lang/StringBuilder;    const-string v6, "the top activity=========="    invoke-direct {v5, v6}, Ljava/lang/StringBuilder;-><init>(Ljava/lang/String;)V    invoke-virtual {v1}, Landroid/content/ComponentName;->getPackageName()Ljava/lang/String;    move-result-object v6    invoke-virtual {v5, v6}, Ljava/lang/StringBuilder;->append(Ljava/lang/String;)Ljava/lang/StringBuilder;    move-result-object v5    invoke-virtual {v5}, Ljava/lang/StringBuilder;->toString()Ljava/lang/String;    move-result-object v5    invoke-static {v4, v5}, Landroid/util/Log;->d(Ljava/lang/String;Ljava/lang/String;)I    .line 887    invoke-virtual {v1}, Landroid/content/ComponentName;->getPackageName()Ljava/lang/String;    move-result-object v4    const-string v5, "com.konka.tvsettings"    invoke-virtual {v4, v5}, Ljava/lang/String;->equals(Ljava/lang/Object;)Z    move-result v4    if-eqz v4, :cond_0    .line 888    const-string v4, "Launcher"    const-string v5, "the TV app is already on the top task list"    invoke-static {v4, v5}, Landroid/util/Log;->w(Ljava/lang/String;Ljava/lang/String;)I    .line 904    :goto_0    return-void    .line 891    :cond_0    invoke-virtual {v1}, Landroid/content/ComponentName;->getPackageName()Ljava/lang/String;    move-result-object v4    const-string v5, "com.konka.avenger"    invoke-virtual {v4, v5}, Ljava/lang/String;->equals(Ljava/lang/Object;)Z    move-result v4    if-eqz v4, :cond_1    .line 892    invoke-virtual {p0}, Lcom/cyanogenmod/trebuchet/Launcher;->closeTVWindow()V    .line 894    const-wide/16 v4, 0x3e8    :try_start_0    invoke-static {v4, v5}, Ljava/lang/Thread;->sleep(J)V    :try_end_0    .catch Ljava/lang/InterruptedException; {:try_start_0 .. :try_end_0} :catch_0    .line 900    :cond_1    :goto_1    new-instance v3, Landroid/content/Intent;    const-string v4, "com.konka.tvsettings.intent.action.RootActivity"    invoke-direct {v3, v4}, Landroid/content/Intent;-><init>(Ljava/lang/String;)V    .line 901    .local v3, intentActivity:Landroid/content/Intent;    const/high16 v4, 0x1020    invoke-virtual {v3, v4}, Landroid/content/Intent;->addFlags(I)Landroid/content/Intent;    .line 903    invoke-virtual {p0}, Lcom/cyanogenmod/trebuchet/Launcher;->getApplicationContext()Landroid/content/Context;    move-result-object v4    invoke-virtual {v4, v3}, Landroid/content/Context;->startActivity(Landroid/content/Intent;)V    goto :goto_0    .line 895    .end local v3           #intentActivity:Landroid/content/Intent;    :catch_0    move-exception v2    .line 896    .local v2, e:Ljava/lang/InterruptedException;    invoke-virtual {v2}, Ljava/lang/InterruptedException;->printStackTrace()V    goto :goto_1.end method

找到：

 new-instance v3, Landroid/content/Intent;    const-string v4, "com.konka.tvsettings.intent.action.RootActivity"    invoke-direct {v3, v4}, Landroid/content/Intent;-><init>(Ljava/lang/String;)V    .line 901    .local v3, intentActivity:Landroid/content/Intent;    const/high16 v4, 0x1020    invoke-virtual {v3, v4}, Landroid/content/Intent;->addFlags(I)Landroid/content/Intent;    .line 903    invoke-virtual {p0}, Lcom/cyanogenmod/trebuchet/Launcher;->getApplicationContext()Landroid/content/Context;    move-result-object v4    invoke-virtual {v4, v3}, Landroid/content/Context;->startActivity(Landroid/content/Intent;)V

看看这儿：

    invoke-direct {v3, v4}, Landroid/content/Intent;-><init>(Ljava/lang/String;)V//看Intent的源码3439    /**3440     * Create an intent with a given action.  All other fields (data, type,3441     * class) are null.  Note that the action <em>must</em> be in a3442     * namespace because Intents are used globally in the system -- for3443     * example the system VIEW action is android.intent.action.VIEW; an3444     * application's custom action would be something like3445     * com.google.app.myapp.CUSTOM_ACTION.3446     *3447     * @param action The Intent action, such as ACTION_VIEW.3448     */3449    public Intent(String action) {3450        setAction(action);3451    }

3、把这段代码，用java表示出来，如下所示：

  /**     * 启动TV。     */    public void startTV()    {        //invoke-direct {v3, v4}, Landroid/content/Intent;-><init>(Ljava/lang/String;)V        Intent it = new Intent("com.konka.tvsettings.intent.action.RootActivity");        it.addFlags(0x1020);        this.startActivity(it);    }

4、写个APK，测试下。测试代码如下

package com.cnblogs.jevan.autostarttv;import com.cnblogs.jevan.autoplaytv.R;import android.os.Bundle;import android.app.Activity;import android.content.Intent;import android.view.Menu;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;/** * 讨厌每次开机都要点击下遥控器的确认键才能播放电视，所以想自己写个应用程序。让塔开机每次都自动进入电视节目。 * @author jevan * @version (1.0 at 2013-6-14) 测试接口。 */public class MainActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);                ((Button)findViewById(R.id.button1)).setOnClickListener(new OnClickListener() {                        @Override            public void onClick(View v) {                // TODO Auto-generated method stub                startTV();            }        });    }    /**     * 启动TV。     */    public void startTV()    {        //invoke-direct {v3, v4}, Landroid/content/Intent;-><init>(Ljava/lang/String;)V        Intent it = new Intent("com.konka.tvsettings.intent.action.RootActivity");        it.addFlags(0x1020);        this.startActivity(it);    }            @Override    public boolean onCreateOptionsMenu(Menu menu) {        // Inflate the menu; this adds items to the action bar if it is present.        getMenuInflater().inflate(R.menu.main, menu);        return true;    }}

5、测试OK，效果正常。增加开机自动运行的功能。

迁移了博客，把代码补全，下面是开机自运行代码：

/** * @author enlangs (http://blog.csdn.net/enlangs) * @version (1.0 at 2013-6-15) 接受开机完成的消息。 * @version 1.2 at 2013-12-15  * */public class AutoRunBroadcastReceiver extends BroadcastReceiver {private final static String TAG = AutoRunBroadcastReceiver.class.getSimpleName();/* (non-Javadoc) * @see android.content.BroadcastReceiver#onReceive(android.content.Context, android.content.Intent) */@Overridepublic void onReceive(Context arg0, Intent arg1) {if(arg1.getAction().equals("android.intent.action.BOOT_COMPLETED")){Log.e(TAG,"=================== onReceive ========================");try {Thread.sleep(5000);//等5秒，給系統5秒时间准备硬件。可能5秒都不够。} catch (InterruptedException e) {e.printStackTrace();}Tools.startTV(arg0);}}}

使用说明：

一定要把应用程序放在/system/app目录下，也就是说，系统必须root，然后使用re文件管理器来移动文件。
