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"

.line 903

move-result-object v4

invoke-virtual {v4, v3}, Landroid/content/Context;->startActivity(Landroid/content/Intent;)V

goto :goto_0

.line 895

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 a
3442     * namespace because Intents are used globally in the system -- for
3443     * example the system VIEW action is android.intent.action.VIEW; an
3444     * application's custom action would be something like
3445     * 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)
*/
@Override
public 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。
