Android 7.1 abnormal deletion of data files causes the HOME key to fail

platform

RK3288 + Android 7.1

problem

使用SU命令删除了/data/system/users目录下的文件后重启, HOME 无法正常返回主界面.

system_process I/WindowManager: Not starting activity because user setup is in progress: Intent { act=android.intent.action.MAIN cat=[android.intent.category.HOME] flg=0x10200000 (has extras) }

    private void startActivityAsUser(Intent intent, UserHandle handle) {
    
    
        if (isUserSetupComplete()) {
    
    
            mContext.startActivityAsUser(intent, handle);
        } else {
    
    
            Slog.i(TAG, "Not starting activity because user setup is in progress: " + intent);
        }
    }

	boolean isUserSetupComplete() {
    
    
        return Settings.Secure.getIntForUser(mContext.getContentResolver(),
                Settings.Secure.USER_SETUP_COMPLETE, 0, UserHandle.USER_CURRENT) != 0;
    }

The value of Settings.Secure.USER_SETUP_COMPLETE is 0?

Method 1:
Command to view the value of the database setting: settings get secure user_setup_complete, the result output is 0

Method 2:
cat /data/system/users/0/settings_secure.xml | grep user_setup

<setting id="56" name="user_setup_complete" value="0" package="com.android.provision" />

solve

使用命令设置为1:

settings put secure user_setup_complete 1

PS

1. The above related commands require system permissions
2. It is recommended to use it only during debugging.
