android 如何在手机第一次开机的时候，把用户放在外置SD卡上的APK自动安装到手机的存储卡。

1. 将APK放到SD卡上某个目录，如apks_preInstall目录.

（对那些有在AndroidManifest.xml中声明了存储路径是internalOnly的apk，不建议使用这种安装方法）

2. 在第一次开机的时候，等sd卡mount上来，去读取这个目录安装APK

实现代码：

1. 修改\packages\apps\PackageInstaller\AndroidManifest.xml

<!-- 增加一个receiver -->

<receiver android:name=".FirstInstallReceiver">

<intent-filter>

<action android:name="android.intent.action.MEDIA_MOUNTED_FOR_FIRTIME" />

</intent-filter>

</receiver>

<!--end -->



2. \packages\apps\PackageInstaller\src\com\android\packageinstaller下增加FirstInstallReceiver.java文件，用于接收第一次SD卡mount上来的广播，以便安装APK，内容如下：

package com.android.packageinstaller;



import android.content.ContentValues;

import android.content.Context;

import android.content.Intent;

import android.content.BroadcastReceiver;

import android.content.IntentFilter;

import android.content.SharedPreferences;

import android.util.Log;

import android.content.pm.IPackageInstallObserver;

import android.content.pm.PackageInfo;

import android.content.pm.PackageManager;

import java.io.File;

import android.net.Uri;



public class FirstInstallReceiver extends BroadcastReceiver{

private final String TAG="FirstInstallReceiver";

private String action = "android.intent.action.MEDIA_MOUNTED_FOR_FIRTIME";



/*下面变量apksPath是外置sd卡上的某个路径, 要修改默认预置的apk存放路径，请修改这个路径。

GB版本、GB2、ICS单卡项目：sd卡路径是/mnt/sdcard

GB2双卡项目: 默认外置sd卡路径是/mnt/sdcard/sdcard2, 如打开SDSwap Feature,外置SD卡路径则是:/mnt/sdcard

ICS双卡项目: 默认外置SD卡路径是/mnt/sdcard2, 如打开SDSwap Feature,外置SD卡路径则是:/mnt/sdcard

因此修改要针对不同情况，首先需要确认外置SD卡的路径。

*/

private String apksPath = "/mnt/sdcard/apks_preInstall"; //这个例子假设外置SD卡路径为/mnt/sdcard ///////////////////////

@Override

public void onReceive(Context context, Intent intent) {

Log.d(TAG,"onReceive:"+intent);

new Thread()

{

public void run() {

try

{

File apksFile = new File(apksPath);

PackageManager pm = context.getPackageManager();

int installFlags = 0;

installFlags |= PackageManager.INSTALL_EXTERNAL;

if(apksFile.exists()) {

File[] files = apksFile.listFiles();

for(File f1:files)

{

String filename = f1.getName();

String type = filename.substring(filename.lastIndexOf(".")+1);

if(type!=null&&type.equals("apk"))

{

Uri mPackageURI = Uri.fromFile(f1);

pm.installPackage(mPackageURI, null, installFlags, null);

}

}

}

}

catch(Exception e)

{

Log.d(TAG,"onReceive:install failed:e:"+e);

}

}

}.start();

}

}



3. 修改mountservice.java， 用于发送第一次开机sd卡mount上来的广播

private void notifyVolumeStateChange(String label, String path, int oldState, int newState) { .....

else if (newState == VolumeState.Mounted) {

//mtk added

String isFirstBoot = SystemProperties.get("persist.sys.mount_is_first");

if(isFirstBoot == null || isFirstBoot.equals(""))

{

Slog.i(TAG, "first boot");

SystemProperties.set("persist.sys.mount_is_first", "DONE");

Intent firIntent = new Intent("android.intent.action.MEDIA_MOUNTED_FOR_FIRTIME");

mContext.sendStickyBroadcast(firIntent);

}

//mtk added



if (DEBUG_EVENTS) Slog.i(TAG, "updating volume state mounted");

updatePublicVolumeState(path, Environment.MEDIA_MOUNTED);

.....
