推荐答案
预装的应用程序位于 /system/app 文件夹中.用户安装的应用程序位于 /data/app 中.我猜你不能访问,除非你有一个根电话.我这里没有root手机,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]); } }
它确实列出了我根深蒂固的 htc 魔法和 emu 中的 apk.
It does lists the apks in my rooted htc magic and in the emu.
