Android 5.0以上获取正在运行的程序的包名

1，在AndroidManifest.xml中配置权限

<uses-permission android:name="android.permission.PACKAGE_USAGE_STATS" tools:ignore="ProtectedPermissions"/>

2，跳转用户授权界面

public boolean checkUsageStats() {
        AppOpsManager appOpt = (AppOpsManager) mContext.getSystemService(Context.APP_OPS_SERVICE);
        int mode = appOpt.checkOpNoThrow(AppOpsManager.OPSTR_GET_USAGE_STATS, android.os.Process.myUid(), mContext.getPackageName());
        boolean isGranted = mode == AppOpsManager.MODE_ALLOWED;
        return isGranted;
    }
private void checkUsageStatsPermission() {
        if (!checkUsageStats()) {
            showToast("请打开权限以获取系统导航状态");
            startActivity(new Intent(Settings.ACTION_USAGE_ACCESS_SETTINGS));
        }
    }

3，获取正在运行的程序

 public boolean getSystemNaviState() {
        String currentApp = "NULL";
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
            UsageStatsManager usm = (UsageStatsManager) mContext.getSystemService(Context.USAGE_STATS_SERVICE);
            long time = System.currentTimeMillis();
            List<UsageStats> appList = usm.queryUsageStats(UsageStatsManager.INTERVAL_DAILY, time - 1000 * 1000, time);
            if (appList != null && appList.size() > 0) {
                SortedMap<Long, UsageStats> mySortedMap = new TreeMap<Long, UsageStats>();
                for (UsageStats usageStats : appList) {
                    mySortedMap.put(usageStats.getLastTimeUsed(), usageStats);
                }
                if (mySortedMap != null && !mySortedMap.isEmpty()) {
                    currentApp = mySortedMap.get(mySortedMap.lastKey()).getPackageName();
                }
            }
        } else {
            ActivityManager am = (ActivityManager) mContext.getSystemService(Context.ACTIVITY_SERVICE);
            List<ActivityManager.RunningAppProcessInfo> tasks = am.getRunningAppProcesses();
            currentApp = tasks.get(0).processName;
        }
        Log.e("adapter", "Current App in foreground is: " + currentApp);
        if (currentApp.contains("com.autonavi")) {
            return true;
        }
        return false;
    }
