在Android O中使用Intent启用自动填充服务失败

Question

我使用了这段代码来启用自动填充服务。

Intent dialogIntent = new Intent(Settings.ACTION_REQUEST_SET_AUTOFILL_SERVICE);
        startActivity(dialogIntent);

我遇到了下一个异常：

Answer 1

您在意图中缺少包名称。请将您的应用程序包名称传递给intent.setData()。

示例：

Intent intent = new Intent(android.provider.Settings.ACTION_REQUEST_SET_AUTOFILL_SERVICE);
intent.setData(Uri.parse("package:<YOUR_APP_PACKAGE_NAME>"));
startActivity(intent)

Answer 2

你的intent中缺少包名。根据javadoc文档:

输入: Intent的数据URI设置为应用程序名称，使用“package”模式（例如“package:com.my.app”）。

Answer 3

在华为设备上，即使您正确检查了 hasEnabledAutofillServices() 和 isAutofillSupported() 并包括包，看起来似乎也会发生这种情况。

我现在正在捕获ActivityNotFoundException并显示一条消息，告诉用户应该在设置中启用自动填充。 - Philipp

你可以使用这个代替捕获异常。getPackageManager().queryIntentActivities(intent, 0).size() > 0 - darrenp
