Android针对5.0前后获取所有进程和App信息

Android5.0版本后对权限的控制更为严格，以下是两个获取应用信息的小demo

1.Android5.0以后获取所有进程信息

下载Github提供的开源5.0以后获取系统进程权限的项目
LZ下载的app_process_library.jar

/**     * 5.0系统以上获取运行的进程方法     *     * @param context     * @param handler     */    public static void getProcesses(final Context context, final ProcessManagerActivity.ProcessHandler handler) {        new Thread() {            public void run() {                try {                    Thread.sleep(1000);                } catch (InterruptedException e) {                    e.printStackTrace();                }                ActivityManager am = PackageUtils.getActivityManager(context);                PackageManager pm = PackageUtils.getPackageManager(context);                List<Object> list = new ArrayList<>();                List<ProcessInfo> userProcessList = new ArrayList<>();                List<ProcessInfo> sysProcessList = new ArrayList<>();                List<AndroidAppProcess> runningAppProcesses = ProcessManager.getRunningAppProcesses();                if (runningAppProcesses != null && runningAppProcesses.size() > 0) {                    for (AndroidAppProcess appProcess : runningAppProcesses) {                        ProcessInfo processInfo = new ProcessInfo();                        processInfo.pid = appProcess.pid;//进程id                        processInfo.processName = appProcess.name;//进程名                        int flags = 0;                        //按包名获取功能清单变量。因为不涉到四大组件                        try {                            PackageInfo packageInfo = pm.getPackageInfo(appProcess.name, flags);                            processInfo.icon = packageInfo.applicationInfo.loadIcon(pm);//图标                            processInfo.name = packageInfo.applicationInfo.loadLabel(pm).toString();//应用名称                            if ((packageInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) == ApplicationInfo.FLAG_SYSTEM) {                                processInfo.isSystemProcess = true;// 是系统进程                                sysProcessList.add(processInfo);                            } else {                                processInfo.isSystemProcess = false;                                userProcessList.add(processInfo);                            }                        } catch (PackageManager.NameNotFoundException e) {                            //info.processName不等于包名才找不到                            e.printStackTrace();//1.系统进程 2.配置process变量的进程                            //针对进程名不等于包名，可以使用小机器人填充                            processInfo.icon = context.getResources().getDrawable(R.drawable.ic_default);                            processInfo.name = appProcess.name;//                            //其它默认为系统                            sysProcessList.add(processInfo);                        }                        //增加一个应用内存的查询 ，针对每一个进程                        //am.getProcessMemoryInfo(pids);查询指定一个进程的内存使用情况(跑跑卡丁车 100M)                        //因为传入的是一个pid返回数组的话 长度为1 ,此时使用0下标来获取数据                        Debug.MemoryInfo memoryInfo = am.getProcessMemoryInfo(new int[]{processInfo.pid})[0];                        processInfo.memory = memoryInfo.getTotalPss() * 1024;                        //getTotalPss()获取进程的使用内存情况获取 long字节数                        //processInfo.memory = memoryInfo.getTotalPss() * 1024;                    }                    //添加标题                    list.add("用户进程(" + userProcessList.size() + ")");                    list.addAll(userProcessList);                    list.add("系统进程(" + sysProcessList.size() + ")");                    list.addAll(sysProcessList);                    //5.4.通知界面进程显示                    Message msg = new Message();                    msg.obj = list;                    msg.what = Constants.PROCESS_INFO_SUCCESS;                    handler.sendMessage(msg);                }            }        }.start();    }

2.Android5.0以前获取所有进程信息

public static void getProcessInfos(final Context context, final ProcessManagerActivity.ProcessHandler handler) {
new Thread() {
public void run() {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
//调用查询方法获取进程列表
