How to get application size + application data size

Question

How can I get the size of the application, including the size of AppData?

I'm currently using this code, but it just gets the size of the APK. Is there a way to get the AppData size, for example, the Google Setting app?

public String getApkSize(Context context, String packageName) {
    try {
        float value = new File(context.getPackageManager().getApplicationInfo(packageName, 0).publicSourceDir).length() / 1048576F;

        if (value <= 0) {
            value = 1;
        }

        return String.format("%.2f", value) + "MB";
    } catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
    }
    return null;
}

The Settings app uses the method getPackageSizeInfo. Unfortunately, this method is hidden because it is annotated with @hide, so you cannot directly use this method, but you need to use reflection to call it.

Add this permission to AndroidManifest.xml:

<uses-permission android:name="android.permission.GET_PACKAGE_SIZE"/>

Create the AIDL interface IPackageStatsObserver:

package android.content.pm;

import android.content.pm.PackageStats;
/**
 * API for package data change related callbacks from the Package Manager.
 * Some usage scenarios include deletion of cache directory, generate
 * statistics related to code, data, cache usage(TODO)
 * {@hide}
 */
oneway interface IPackageStatsObserver {

    void onGetStatsCompleted(in PackageStats pStats, boolean succeeded);
}

:

private void getPackageSizeInfo(Context context, String packageName) {
    try {
        PackageManager packageManager = context.getPackageManager();
        Method getPackageSizeInfo = packageManager.getClass().getMethod("getPackageSizeInfo", String.class, IPackageStatsObserver.class);

        getPackageSizeInfo.invoke(packageManager, packageName, new IPackageStatsObserver.Stub() {
            public void onGetStatsCompleted(PackageStats packageStats, boolean succeeded) throws RemoteException {
                long totalCacheSize = packageStats.cacheSize + packageStats.externalCacheSize;
                long totalDataSize = packageStats.dataSize + packageStats.externalDataSize;
                long totalCodeSize = packageStats.codeSize + packageStats.externalCodeSize;
                long totalSize = totalDataSize + totalCodeSize;

                Log.d(TAG, "Total Size:" + totalSize);
                Log.d(TAG, "App Size:" + totalCodeSize);
                Log.d(TAG, "Data Size:" + totalDataSize);
                Log.d(TAG, "Cache Size:" + totalCacheSize);
            }
        });
    } catch (Exception e) {
        e.printStackTrace();
    }
}

, . , .

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);
        }
    });
