㈠ 请问android APP 如何防止被系统杀死和用户卸载
这个有点流氓软件的味道了……
如果是防止被杀,参照一下这里吧(Android开发之如何保证Service不被杀掉)
如果要防止用户卸载,可以用辅助功能监听用户是否点开了软件卸载页面,如果点开了,查找页面文字或ID,检测一下是不是你的软件,如果是就点取消。但是需要引导用户把辅助功能打开。
建议不要这么做,防止被杀可以,但是防止卸载如果被举报会招到官司的。
㈡ android程序如何监听到自己被卸载这个事件。
手段略曲折
首先给你的程序注册读取log权限,
<uses-permissionandroid:name="android.permission.READ_LOGS"/>
然后在你的程序里开一个后台线程,不停的读取log,当你的应用(包括其他任何应用)被卸载时,系统的ActivityManager会打印出一行log,大概是removing:你的包名。这个时机是在卸载界面点击确定后的一瞬间触发的,如下图
但是不能保证用户就会点确定真把你的卸载了。。所以自己权衡吧。
这是我在网上找到的唯一方法
代码如下:
privatevoidListenLog(){
Threadt=newThread(newRunnable(){
publicvoidrun(){
//TODOAuto-generatedmethodstub
Log.v("Fuck","Startlisteninglog");
String[]cmds={"logcat","-c"};
StringshellCmd="logcat";
Processprocess=null;
InputStreamis=null;
DataInputStreamdis=null;
Stringline="";
Runtimeruntime=Runtime.getRuntime();
try{
intwaitValue;
waitValue=runtime.exec(cmds).waitFor();
process=runtime.exec(shellCmd);
is=process.getInputStream();
dis=newDataInputStream(is);
while((line=dis.readLine())!=null&&mKeepListenFlag){
if(!line.contains("Fuck")){
Log.v("Fuck",line);
//这里只是把每个log都打印了一遍,可以再此判断line里是否有removing字样,然后做些处理
}
}
Log.v("Fuck","finishedlisten");
}catch(InterruptedExceptione){
e.printStackTrace();
}catch(IOExceptionie){
ie.printStackTrace();
}finally{
try{
if(dis!=null){
dis.close();
}
if(is!=null){
is.close();
}
if(process!=null){
process.destroy();
}
}catch(Exceptione){
e.printStackTrace();
}
}
}
});
//mKeepListenFlag是个成员变量,是为了让程序结束时终止线程的,否则可能产生程序多次启动,然后这个线程就启动了多个。Android线程可不会因为Activity的退出而终止。
mKeepListenFlag=true;
t.start();
}
㈢ android程序怎样监听自身程序被安装和卸载
在android系统中,安装和卸载都会发送广播,当应用安装完成后系统会发android.intent.action.PACKAGE_ADDED广播。可以通过intent.getDataString()获得所安装的包名。当卸载程序时系统发android.intent.action.PACKAGE_REMOVED广播。同样intent.getDataString()获得所卸载的包名。
㈣ android应用是如何监听自己是否被卸载的呢
Activity启动时fork出C端进程轮询目录:
1 package main.activity;
2
3 import pym.test.uninstalledmoniter.R;
4 import android.app.Activity;
5 import android.os.Bundle;
6 import android.util.Log;
7
8 /**

10 * @note 监听此应用是否被卸载,若被卸载则弹出卸载反馈

注1:为了调试方便,包含<android/log.h>,使得so在执行过程中也可以像Java端一样方便得打出log。相应的mk文件需要加上以下两句声明
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include
LOCAL_LDLIBS += -L$(SYSROOT)/usr/lib -llog
㈤ android程序怎样监听自身程序被安装和卸载
这个我想到的就一种方法,读取Log信息,然后判断是否被安装,其实系统安装成功之后,会发广播的,很详细,但是这种广播最好是第三方软件坚定为好,自己就没法监听,我前一阵子做升级,就像用这个,但是没用成,最后只是下载apk成功之后,发送给服务器日志信息,感觉自己监听自己,功能实现上好像有些矛盾,个人意见..
㈥ android如何监听自身的卸载操作
答案是不行。官方文档说了卸载的app本身,是接收不到卸载的广播的。
㈦ Android应用如何监听自己是否被卸载及卸载反馈功能的实现
刚看了sdk,发现有个:android.bluetooth.BluetoothAdapter.ACTION_STATE_CHANGED
这是个广播
Broadcast Action: The state of the local Bluetooth adapter has been changed.
For example, Bluetooth has been turned on or off.
可蚂激困以监听到蓝牙打开铅粗和关闷念闭。想要更多的自己去查查吧
