本文将通过读取已安装应用列表，如何获取应用列表，和为什么要获取已安装应用列表展开。

Android 读取已安装应用列表需要申请权限吗？

Android 如何完整的获取到用户已安装应用列表

为什么安卓的APP都要读取手机中已安装的应用列表

结合上述三篇文章，选择已下折中方案：

思路：

1.使用adb指令获取包名

private void runCommand() {

try {

Process process = Runtime.getRuntime().exec("adb shell pm list package -3");

BufferedReader bis = new BufferedReader(new InputStreamReader(process.getInputStream()));

String line = null;

while ((line = bis.readLine()) != null) {

System.out.println("runCommand, line=" + line);

}

} catch (IOException e) {

System.out.println("runCommand,e=" + e);

}

}

2.根据包名使用PackageManager获取app的实际名字

private void getAppList() {

PackageManager pm = getPackageManager();

// Return a List of all packages that are installed on the device.

List packages = pm.getInstalledPackages(0);

for (PackageInfo packageInfo : packages) {

// 判断系统/非系统应用

if ((packageInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) == 0) // 非系统应用

{

System.out.println("getAppList, packageInfo=" + packageInfo.packageName);

} else {

// 系统应用

}

}

}

3.结合使用

private void runCommand() {

try {

PackageManager pm = getPackageManager();

Process process = Runtime.getRuntime().exec("adb shell pm list package -3");

BufferedReader bis = new BufferedReader(new InputStreamReader(process.getInputStream()));

String line = null;

while ((line = bis.readLine()) != null) {

PackageInfo packageInfo = App.instance.getPackageManager().getPackageInfo(line.replace("package:", ""), PackageManager.GET_GIDS);

System.out.println("runCommand, line=" + line+"packageInfo.packageName" + ":" + packageInfo.applicationInfo.loadLabel(pm).toString());

}

} catch (IOException e) {

System.out.println("runCommand,e=" + e);

}

}
