androidadb 权限改动

IT知识android

亦余心之所善兮，虽九死其犹未悔。这篇文章主要讲述androidadb 权限改动相关的知识，希望能为你提供帮助。
1. 改动 ADB ROOT权限:
system/core$ git diff adb/adb.c
diff --git a/adb/adb.c b/adb/adb.c
index 99bea0f..d8fc090 100644
--- a/adb/adb.c
+ + + b/adb/adb.c

+       char value[PROPERTY_VALUE_MAX];
+       property_get(" hw.hasusbadbroot" , value, " " );
+       if(strcmp(value, " 1" ) == 0)
+       return 0;
+ else
      return 1;
  #else /* ALLOW_ADBD_ROOT */
      int secure = 0;

同一时候在system.prop中加入hw.hasusbadbroot=1




2.去掉adb 密钥校验：
ro.adb.secure=0



3.改动开发人员选项隐藏
packages/apps/Settings/src/com/android/settings/Settings.java


      private void updateHeaderList(List< Header> target) {
-         final boolean showDev = mDevelopmentPreferences.getBoolean(
-                 DevelopmentSettings.PREF_SHOW,
