Examples with PackageStats android.content.pm.PackageStats used on opensource projects

Example 1 with PackageStats

use of android.content.pm.PackageStats in project android_frameworks_base by ParanoidAndroid.

the class PackageManagerService method getPackageSizeInfo.

public void getPackageSizeInfo(final String packageName, int userHandle, final IPackageStatsObserver observer) {
    mContext.enforceCallingOrSelfPermission(android.Manifest.permission.GET_PACKAGE_SIZE, null);
    PackageStats stats = new PackageStats(packageName, userHandle);
    /*
         * Queue up an async operation since the package measurement may take a
         * little while.
         */
    Message msg = mHandler.obtainMessage(INIT_COPY);
    msg.obj = new MeasureParams(stats, observer);
    mHandler.sendMessage(msg);
}

Example 2 with PackageStats

use of android.content.pm.PackageStats in project superCleanMaster by joyoyao.

the class CacheInfoProvider method initDataSize.

/**
	 * 通过AIDL的方法来获取到应用的缓存信息，getPackageSizeInfo是PackageManager里面的一个私有方法来的
	 * 我们通过反射就可以调用到它的了，但是这个方法里面会传递一个IPackageStatsObserver.Stub的对象
	 * 里面就可能通过AIDL来获取我们想要的信息了
	 * 
	 * 因为这样的调用是异步的，所以当我们完成获取完这些信息之后，我们就通过handler来发送一个消息
	 * 来通知我们的应用，通过getCacheInfos来获取到我们的Vector
	 * 
	 * 为什么要用Vector呢，因为下面的方法是异步的，也就是有可能是多线程操作，所以我们就用了线程安全的Vector
	 * 
	 * @param cacheInfo
	 * @param position
	 */

                if (position == (size - 1)) {
                    // 当完全获取完信息之后，发送一个成功的消息
                    // 1对应的就是CacheClearActivity里面的FINISH
