问题描述
android 从 Marketplace 安装应用程序后,它会保留 .apk 文件吗?
After android installs an application from the Marketplace, does it keep the .apk file?
Android 是否有标准位置来保存此类文件?
Is there a standard location where Android would keep such files?
推荐答案
预安装的应用程序位于 /system/app
文件夹中.用户安装的应用程序位于 /data/app
中.我想除非你有一个root手机,否则你无法访问.我这里没有根电话,但试试这个代码:
Preinstalled applications are in /system/app
folder. User installed applications are in /data/app
. I guess you can't access unless you have a rooted phone.I don't have a rooted phone here but try this code out:
public class Testing extends Activity {
private static final String TAG = "TEST";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
File appsDir = new File("/data/app");
String[] files = appsDir.list();
for (int i = 0 ; i < files.length ; i++ ) {
Log.d(TAG, "File: "+files[i]);
}
}
它确实列出了我根植的 htc magic 和 emu 中的 apk.
It does lists the apks in my rooted htc magic and in the emu.
