}
private void checkOutOfSpace(long size) {

}
以下是在PackageManagerService的:
Java代码
public void freeStorageAndNotify(final long freeStorageSize, final IPackageDataObserver observer) {
mContext.enforceCallingOrSelfPermission(
android.Manifest.permission.CLEAR_APP_CACHE, null);
// Queue up an async operation since clearing cache may take a little while.
mHandler.post(new Runnable() {
public void run() {
mHandler.removeCallbacks(this);
int retCode = -1;
if (mInstaller != null) {
retCode = mInstaller.freeCache(freeStorageSize);
if (retCode < 0) {
Slog.w(TAG, "Couldn't clear application caches");
}
} //end if mInstaller
if (observer != null) {
try {
observer.onRemoveCompleted(null, (retCode >= 0));
} catch (RemoteException e) {
Slog.w(TAG, "RemoveException when invoking call back");
}
}
}
});
}
