无法确定Android设备上是否安装了Google play store

Question

private static final String GooglePlayStorePackageName = "com.google.market";

void someMethod() {
    packageManager = getApplication().getPackageManager();
    List<PackageInfo> packages = packageManager.getInstalledPackages(PackageManager.GET_UNINSTALLED_PACKAGES);
    for (PackageInfo packageInfo : packages) {
        if (packageInfo.packageName.equals(GooglePlayStorePackageName)) {
            googlePlayStoreInstalled = true;
            break;
        }
    }
}

包名称更改了吗？或者我看错了方向？

谢谢,

亚当。

protected final boolean isPackageInstalled(String packageName) {
    try {
        application.getPackageManager().getPackageInfo(packageName, 0);
    } catch (NameNotFoundException e) {
        return false;
    }
    return true;
}

请注意，这几乎5年的代码是不是最优的，谷歌不喜欢当你检查所有安装的软件包没有充分的理由。请同时检查其他答案。

包名已更改，现在是com.android.vending

尝试：

private static final String GooglePlayStorePackageNameOld = "com.google.market";
private static final String GooglePlayStorePackageNameNew = "com.android.vending";

void someMethod() {
    PackageManager packageManager = getApplication().getPackageManager();
    List<PackageInfo> packages = packageManager.getInstalledPackages(PackageManager.GET_UNINSTALLED_PACKAGES);
    for (PackageInfo packageInfo : packages) {
        if (packageInfo.packageName.equals(GooglePlayStorePackageNameOld) ||
            packageInfo.packageName.equals(GooglePlayStorePackageNameNew)) {
            googlePlayStoreInstalled = true;
            break;
        }
    }
}
