friend of the Chinese version of Android APK, you should be familiar with these tools: The first tool is Android-apktool, a tool for reengineering Android APK files. This tool is the core of APK crack. It is used to decompile and

mechanism of apk. 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

to sign the APK, but using Gradle is easier. Such as:You may not want to tell the password hard-coded to the build file, you can put them in the Gradle.properties file or set it on the command line.In the DSL document, the Signingconfigs block is delegated to the Signingconfig class, which has four commonly used properties:Keyalias: This value is used when Keytool signs a specific keyKeypassword: The password of the key used in the signing processSto

check the integrity of applications. We can use jni technology to verify the integrity of applications, or use digital signatures to detect the integrity of applications. We know that after an apk file is decompiled and cracked and the code logic is modified, we need to use the jarsigner tool to re-sign the apk to run the modified apk file. The signature of an a

so that the Anti-compilation tool (Jd-gui) cannot decompile and query your Java code. Jd-gui Bug actually quite a lot of, many special code block or field set can let it crash cannot decompile source code.Like what:private static final char[] WJ = "0123456789abcdef".
