AppUsageProvider.java

public boolean onCreate() {

matcher.addURI(HSApplication.getContext().getPackageName() + "." + this.getClass().getName(), "query_app_usage", 1);

matcher.addURI(HSApplication.getContext().getPackageName() + "." + this.getClass().getName(), "query_app_mobile_usage", 2);

matcher.addURI(HSApplication.getContext().getPackageName() + "." + this.getClass().getName(), "query_app_mobile_usage_detail", 3);

return true;

}

HSApplication.getContext() 这个方法 return的Context是在Application attachBaseContext 赋的值

加固之前运行正常

java

android
