Copy the libray module to the project, or directly rely on the following in build.gradle:
allprojects {
repositories {
maven { url 'https://jitpack.io' }
}
}
dependencies {
compile 'com.github.AnJiaoDe:Permission:V1.0.0'
}
Note: if sync reports an error, it is related to com.android.tools.build:gradle 3.0,
You can change compile to implementation or api instead
For Android 6.0 and above, the danger permission must be dynamically requested, and the danger permission is divided into groups
1. All allowed
2. refusal
3. refusal
4. The user refuses and selects no more queries. The pop-up window allows the user to authorize
5. The user agreed to the authorization and closed the authorization when he was busy
