Android解析SD卡上的APK檔案，android解析sdapk

public void parseApk(Context context, String apkFilePath){    PackageManager packageManager = context.getPackageManager();    PackageInfo packageInfo = packageManager.getPackageArchiveInfo(apkFilePath, 0);    if(packageInfo != null){        packageInfo.applicationInfo.sourceDir = apkFilePath;        packageInfo.applicationInfo.publicSourceDir = apkFilePath;        String name = packageInfo.applicationInfo.loadLabel(packageManager).toString();        String packageName = packageInfo.packageName;        String versionName = packageInfo.versionName;        int versionCode = packageInfo.versionCode;        Drawable iconDrawable = packageInfo.applicationInfo.loadIcon(packageManager);    }}

需要注意的是在得到packageInfo後必須要設定applicationInfo的sourceDir和publicSourceDir，否則你在讀取label的時候會輸出如下錯誤資訊並拋出異常
Failure retrieving text 0x7f050000 in package com.taskkiller.demo

你讀icon的時候會輸出如下錯誤資訊並拋出異常
Failure retrieving icon 0x7f020005 in package com.sample.radio

這是因為label和icon都是在資源裡面的，不設定sourceDir和publicSourceDir就不能讀取資源裡面的資訊
