Even so, it sounds a little excited, isn't it?Working Principle As shown in, the host Program loads the apk to the file system, such as the SD card, and then executes the activity in the apk through an activity called proxy. In theory, DexClassLoader, PathClassLoader, and URLClassLoader can be used for dynamic

Recently Tinker Android, encountered a problem, because there is no root permissions, need to invoke intent installation apk, but need to get the user is installed (such as, the user clicked back or cancel), check a lot of articles, and finally can be resolved, but there are flaws, the solution is as follows: public static void InstallPackage (context, file, int requestcode) {//before installation records

Later, we thought that similar Android malware had already been released, indicating that many software security experts or hackers are familiar with this. As a evangelist, I only tell you the secrets that a few people know. As a result, I

Android obtains information about installed and not installed apk. PackageManager is the most important class for obtaining apk resources. We can use this class to get all kinds of things we want. First, we can get the basic information of installed apk, including label, and icons: PackageManager pm = getPackageManage

to set this flag bit to 1 to achieve our goal. Android PackageManagerService does not care about this encrypted Bit During apk installation (we will call it this for the time being) it can be installed normally without affecting the running of apk. Ii. zip file format The zip file format consists of three parts: compressed file source data, compressed directory

In fact, in consideration of the security mechanism of applications, we hope that ou

For example, take C

On an article we talked about APK to prevent anti-compilation technology in the shell technology, if there is not clear can view my previous blog http://my.oschina.net/u/2323218/blog/393372. Next we will introduce another technique to prevent the apk from recompiling-modifying bytecode at runtime. This method is in the work in the implementation of the app wrapping, see a foreign article about the security
