java – Oreo中的RecognizerIntent.ACTION_GET_LANGUAGE_DETAILS

在大多数Android设备中,RecognitionService将由Google的原生“现在/助理”应用程序提供.

在Android Oreo之前,我能够使用以下简单代码查询Google Recognizer支持的语言：

final Intent vrIntent = new Intent(RecognizerIntent.ACTION_GET_LANGUAGE_DETAILS);

// vrIntent.setPackage("com.google.android.googlequicksearchbox");

getContext().sendOrderedBroadcast(vrIntent, null, new BroadcastReceiver() {

    @Override
    public void onReceive(final Context context, final Intent intent) {

                // final Bundle bundle = intent.getExtras();
                final Bundle bundle = getResultExtras(true);

                if (bundle != null) {

                    if (bundle.containsKey(RecognizerIntent.EXTRA_SUPPORTED_LANGUAGES)) {
                        Log.i("TAG", "onReceive: EXTRA_SUPPORTED_LANGUAGES present");

                        final ArrayList<String> vrStringLocales = bundle.getStringArrayList(
                                RecognizerIntent.EXTRA_SUPPORTED_LANGUAGES);

                        Log.i("TAG", "onReceive: EXTRA_SUPPORTED_LANGUAGES size: " + vrStringLocales.size());

                    } else {
                        Log.w("TAG", "onReceive: missing EXTRA_SUPPORTED_LANGUAGES");
                    }

                } else {
                    Log.w("TAG", "onReceive: Bundle null");
                }

}, null, 1234, null, null);

但是,从8.0开始,响应中不再包含额外的RecognizerIntent.EXTRA_SUPPORTED_LANGUAGES.

在我尝试将此文件作为错误提交之前,我想首先看看其他人是否可以复制 – 但是还要检查是否存在订单广播behavioural change in API 26我有点忽略了,这可能是导致这种情况的原因.

提前致谢.

解决方法:

因此,如果您没有设置包名,我无法复制,但可以进一步复制注释

vrIntent.setPackage("com.google.android.googlequicksearchbox");

然后它失败了,否则一切正常.

这是我用来测试它的基本活动.

package it.versionestabile.stackover001;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.speech.RecognizerIntent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;

import java.util.ArrayList;

import static java.security.AccessController.getContext;

/**

 */
public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final Intent vrIntent = new Intent(RecognizerIntent.ACTION_GET_LANGUAGE_DETAILS);
        vrIntent.setPackage("com.google.android.googlequicksearchbox");

        PackageManager packageManager = getPackageManager();

        for (PackageInfo packageInfo: packageManager.getInstalledPackages(0)) {
            if (packageInfo.packageName.contains("com.google.android.googlequicksearchbox"))
                Log.d("AAA", packageInfo.packageName + ", "  + packageInfo.versionName);
        }

        this.sendOrderedBroadcast(vrIntent, null, new BroadcastReceiver() {

            @Override
            public void onReceive(final Context context, final Intent intent) {

                // final Bundle bundle = intent.getExtras();
                final Bundle bundle = getResultExtras(true);

                if (bundle != null) {

                    if (bundle.containsKey(RecognizerIntent.EXTRA_SUPPORTED_LANGUAGES)) {
                        Log.i("TAG", "onReceive: EXTRA_SUPPORTED_LANGUAGES present");

                        final ArrayList<String> vrStringLocales = bundle.getStringArrayList(
                                RecognizerIntent.EXTRA_SUPPORTED_LANGUAGES);

                        Log.i("TAG", "onReceive: EXTRA_SUPPORTED_LANGUAGES size: " + vrStringLocales.size());

                    } else {
                        Log.w("TAG", "onReceive: missing EXTRA_SUPPORTED_LANGUAGES");
                    }

                } else {
                    Log.w("TAG", "onReceive: Bundle null");
                }
            }

            }, null, 1234, null, null);
    }
}

我已经在Android Studio 2.3和3.0.1以及使用API​​ 26和27的模拟器上测试了它.

一切正常,上面的代码.

但如果你注释掉这一行：

vrIntent.setPackage("com.google.android.googlequicksearchbox");

在奥利奥它不起作用.

我仍然建议以这样的方式检查Google即时与包管理器的存在：

PackageManager packageManager = getPackageManager();

for (PackageInfo packageInfo: packageManager.getInstalledPackages(0)) {
    if (packageInfo.packageName.contains("com.google.android.googlequicksearchbox"))
        Log.d("AAA", packageInfo.packageName + ", "  + packageInfo.versionName);
// TODO - set a boolean value to discriminate the precence of google now
}

为了确定您是否拥有正确的Google即时版本.

希望能帮助到你！
