如何獲得 package 名稱？

Question

如何顯示我手機中安裝的所有應用程序的所有 package 名稱。 還添加按鈕以打開該應用程序的直接設置。

我想檢查手機上是否有特定的應用程序 package 可用。

final String appPackageName = getPackageName(); // getPackageName() from Context or Activity object
                    try {
                        startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + packageName)));
                    } catch (android.content.ActivityNotFoundException anfe) {
                        startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + packageName)));

Answer 1

嘗試這個：

final PackageManager packageManager = getPackageManager();

List<ApplicationInfo> packages =   packageManager.getInstalledApplications(PackageManager.GET_META_DATA);

for (ApplicationInfo packageInfo : packages) {
  Log.d(TAG, "Installed package :" + packageInfo.packageName);
  Log.d(TAG, "Source dir : " + packageInfo.sourceDir);
  Log.d(TAG, "Launch Activity :" + packageManager.getLaunchIntentForPackage(packageInfo.packageName)); 
}
