I'm trying to get the size occupied by my application package. Every application has one location in the internal/external storage.
I want to calculate the size of the following directory, how can I do that? I know I can use StorageStateManager on and above Oreo (API 26) devices, but how can I achieve this before oreo devices.
Application Directory : /Android/data/myapplicationpackage
I'm trying to use PackageStats but It's giving me always zero. What's the actual way to use this code?
I used the following code and it gives me all zero.
PackageStats stats = new PackageStats(context.getPackageName());
long codeSize = stats.codeSize + stats.externalCodeSize;
long dataSize = stats.dataSize + stats.externalDataSize;
long cacheSize = stats.cacheSize + stats.externalCacheSize;
long appSize = codeSize + dataSize + cacheSize;
PackageStats stats = new PackageStats(context.getPackageName());
It will only creates the packagestats object. As from the source, the constructor will do initializing the fields,
public PackageStats(String pkgName) {
packageName = pkgName;
userHandle = UserHandle.myUserId();
}
for api<26,
You need to use IPackageStatsObserver.aidl
and have to invoke getPackageSizeInfo
method by reflection.
PackageManager pm = getPackageManager();
Method getPackageSizeInfo = pm.getClass().getMethod(
"getPackageSizeInfo", String.class, IPackageStatsObserver.class);
getPackageSizeInfo.invoke(pm, "com.yourpackage",
new IPackageStatsObserver.Stub() {
@Override
public void onGetStatsCompleted(PackageStats pStats, boolean succeeded)
throws RemoteException {
//here the pStats has all the details of the package
}
});
Here is the complete solution for it. It works great.
from api 26,
The getPackageSizeInfo
method is deprecated.
You can use this code,
@SuppressLint("WrongConstant")
final StorageStatsManager storageStatsManager = (StorageStatsManager) context.getSystemService(Context.STORAGE_STATS_SERVICE);
final StorageManager storageManager = (StorageManager) context.getSystemService(Context.STORAGE_SERVICE);
try {
ApplicationInfo ai = context.getPackageManager().getApplicationInfo(packagename, 0);
StorageStats storageStats = storageStatsManager.queryStatsForUid(ai.storageUuid, info.uid);
cacheSize =storageStats.getCacheBytes();
dataSize =storageStats.getDataBytes();
apkSize =storageStats.getAppBytes();
size+=info.cacheSize;
} catch (Exception e) {}
But to use this code, You need USAGE ACCESS PERMISSION .
