查找已安装应用程序的 APK 大小 [英] find the APK size of installed applications

问题描述

我正在尝试计算已安装应用程序的 apk 文件大小.这是代码

I am trying to calculate apk file size of the installed applications. Here is the code

 public class PackageTabActivity extends ListActivity{

  private static final String APP_NAME = "app_name";
  private static final String APP_ICON = "app_icon";
  private static final String APP_SIZE = "app_size";
  Method getPackageSizeInfo = null;
  PackageManager pm  ;
@Override
public void onCreate(Bundle icicle){
    super.onCreate(icicle);
    pm = getPackageManager();


    try {
        getPackageSizeInfo = pm.getClass().getMethod("getPackageSizeInfo", String.class, IPackageStatsObserver.class);
    } catch (SecurityException e1) {

        e1.printStackTrace();
    } catch (NoSuchMethodException e1) {

        e1.printStackTrace();
    } 
    new AppDetails().execute();
}

private boolean isSystemPackage(PackageInfo pkgInfo) {
    return ((pkgInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0) ? true
            : false;
}


class AppDetails extends AsyncTask<Void, Void, ArrayList<HashMap<String , Object>>>
{
     private  long   app_apk_size;
     ProgressDialog mDialog;
     @Override
     public void onPreExecute()
     {
             mDialog = new ProgressDialog(PackageTabActivity.this);
             mDialog.setCancelable(true);
             mDialog.setMessage("Loading... " );
             mDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
             mDialog.setProgress(0);
             mDialog.show();
     }
    @Override
    protected ArrayList<HashMap<String, Object>> doInBackground(
            Void... params) {

        ArrayList<HashMap<String,Object>> applistwithicon = new ArrayList<HashMap<String,Object>>();
        HashMap<String,Object> hm;
        String appname;
        Drawable icon = null;
        List<PackageInfo> packs = getPackageManager().getInstalledPackages(0);   

        for(int i=0;i<packs.size();i++) {

            PackageInfo p = packs.get(i);


            if(!isSystemPackage(p))
            {
                hm = new HashMap<String, Object>();
                appname = p.applicationInfo.loadLabel(getPackageManager()).toString();

                icon = p.applicationInfo.loadIcon(getPackageManager());
                Log.v("package name", "package name =" + p.packageName);
                try {
                  getPackageSizeInfo.invoke(pm,  p.packageName, new IPackageStatsObserver.Stub()  {

                    public void onGetStatsCompleted(PackageStats pStats, boolean succeeded) throws RemoteException {

                                   app_apk_size = pStats.codeSize;    
                                   Log.v("apksize", "appsize = "+app_apk_size);
                    }           
            });
                }catch(IllegalAccessException e) {}
                catch(IllegalArgumentException r) {}
                catch(InvocationTargetException w){}

            hm.put(APP_SIZE, (app_apk_size/(1024)));
            hm.put(APP_ICON, icon);
            hm.put(APP_NAME, appname);
            applistwithicon.add(hm);
            }
        }

        return applistwithicon;
    }
    @Override
    public void onPostExecute(ArrayList<HashMap<String, Object>> result)
    {
        mDialog.dismiss();
         CustomAdapterList myAdapter = new CustomAdapterList(result,PackageTabActivity.this );

          setListAdapter(myAdapter);

    }
}
}

这里的 IPackageStatsObserver 是一个接口(aidl 文件).这给了我在模拟器上但在电话上的正确结果.它给出了正确和错误的应用程序大小的混合.

Here IPackageStatsObserver is an interface (aidl file). This gives me correct result on emulator but on phone. It gives mixture of right and wrong size of application.

我现在完全卡住了，找不到任何解决方法.

I am now totally stuck and can't find any workaround.

非常感谢任何帮助.

推荐答案

这是 Joseph 的一个对我有用的技巧.他的原始帖子可以在这里

Here is a hack from Joseph that worked for me. His original post can be found here

PackageManager pm = getPackageManager();

Method getPackageSizeInfo = pm.getClass().getMethod(
    "getPackageSizeInfo", String.class, IPackageStatsObserver.class);

getPackageSizeInfo.invoke(pm, "com.android.mms",
    new IPackageStatsObserver.Stub() {

        @Override
        public void onGetStatsCompleted(PackageStats pStats, boolean succeeded)
            throws RemoteException {

            Log.i(TAG, "codeSize: " + pStats.codeSize);
        }
    });
