Android 获取应用安装路径：Java 代码示例

要获取当前 Android 应用的安装路径，可以使用以下方法：

1. 使用'getPackageManager()'方法获取'PackageManager'对象：

PackageManager packageManager = getPackageManager();

2. 使用'getPackageInfo()'方法获取'PackageInfo'对象：

String packageName = getPackageName();
PackageInfo packageInfo = packageManager.getPackageInfo(packageName, 0);

3. 从'PackageInfo'对象中获取应用的安装路径：

String appInstallPath = packageInfo.applicationInfo.sourceDir;

完整的代码示例：

PackageManager packageManager = getPackageManager();
String packageName = getPackageName();
try {
    PackageInfo packageInfo = packageManager.getPackageInfo(packageName, 0);
    String appInstallPath = packageInfo.applicationInfo.sourceDir;
    Log.d('AppInstallPath', appInstallPath);
} catch (PackageManager.NameNotFoundException e) {
    e.printStackTrace();
}
