Android 应用程序在 FragmentActivity.java android.support.v4.app.FragmentActivity.startActivityForResult 上崩溃

Question

在我的应用程序中，它们不是 FragmentActivity.java，但崩溃报告给了我以下错误

Fatal Exception: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=market://details?id=com.google.android.gms&pcampaignid=gcore_8487000--- flg=0x80000 pkg=com.android.vending }

我不知道问题到底是什么、出在哪里，而且大多数时候这种崩溃发生在红米手机上

如果设备未安装 google play(没有 Activity 来处理此 intent)，则会发生异常 - 您可以尝试在浏览器中打开网址 在这种情况下:

您可以使用google play包名称:com.android.vending

String pakcage_name="com.android.vending";

 public static void open_google_play(Context context) {
    try {
        //open in play store app directly
        context.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + pakcage_name)));
    } catch (android.content.ActivityNotFoundException e) {
        //open in browser
        openBrowser(context, "https://play.google.com/store/apps/details?id=" + pakcage_name);
    }
}

public static void openBrowser(Context context, String url) {
    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
    if (null != intent.resolveActivity(context.getPackageManager())) {
        context.startActivity(intent);
    }
}

在按钮单击期间使用它，编写此方法:

open_google_play(Activity.this);
