判断apk是否是完整并可以正常安装的apk包，

public boolean getUninatllApkInfo(Context context,String filePath) {
boolean result = false;
try {
PackageManager pm = context.getPackageManager();
Log.e("archiveFilePath", filePath);
PackageInfo info = pm.getPackageArchiveInfo(filePath,PackageManager.GET_ACTIVITIES);
if (info != null) {
result = true;//完整
}
} catch (Exception e) {
result = false;//不完整
}
return result;
}
