Question

我试图使用react-native-push-notifications。它全部在iOS上工作，但在android上我得到undefined不是一个对象（评估RNPushnotification.getInitialNotifications）。

这是我的build.gradle

dependencies {
    compile project(':react-native-push-notification')
    compile project(':react-native-vector-icons')
    compile fileTree(dir: "libs", include: ["*.jar"])
    compile "com.android.support:appcompat-v7:23.0.1"
    compile "com.facebook.react:react-native:+"  // From node_modules
    compile project(':react-native-push-notification')
    compile ('com.google.android.gms:play-services-gcm:8.1.0') {
        force = true;
    }
}

这是我的manifestfile：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.tzawajna"
    android:versionCode="1"
    android:versionName="1.0">

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <permission
        android:name="${applicationId}.permission.C2D_MESSAGE"
        android:protectionLevel="signature" />
    <uses-permission android:name="com.tzawajna.permission.C2D_MESSAGE" />
    <uses-permission android:name="android.permission.VIBRATE" />
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

    <uses-sdk
        android:minSdkVersion="16"
        android:targetSdkVersion="22" />

    <application
      android:name=".MainApplication"
      android:allowBackup="true"
      android:label="@string/app_name"
      android:icon="@mipmap/ic_launcher"
      android:theme="@style/AppTheme">
      <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
        android:windowSoftInputMode="adjustResize">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
      </activity>
      <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
      <receiver
            android:name="com.google.android.gms.gcm.GcmReceiver"
            android:exported="true"
            android:permission="com.google.android.c2dm.permission.SEND" >
            <intent-filter>
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
                <category android:name="com.tzawajna" />
            </intent-filter>
        </receiver>

        <receiver android:name="com.dieam.reactnativepushnotification.modules.RNPushNotificationPublisher" />

        <receiver android:name="com.dieam.reactnativepushnotification.modules.RNPushNotificationBootEventReceiver">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
        </receiver>

        <service android:name="com.dieam.reactnativepushnotification.modules.RNPushNotificationRegistrationService"/>
        <service
            android:name="com.dieam.reactnativepushnotification.modules.RNPushNotificationListenerService"
            android:exported="false" >
            <intent-filter>
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            </intent-filter>
        </service>

    </application>

</manifest>

这是我的MainApplication.java

package (My app);

import android.app.Application;

import com.facebook.react.ReactApplication;
import com.facebook.react.ReactNativeHost;
import com.facebook.react.ReactPackage;
import com.facebook.react.shell.MainReactPackage;
import com.facebook.soloader.SoLoader;

import java.util.Arrays;
import java.util.List;

public class MainApplication extends Application implements ReactApplication {

  private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {
    @Override
    public boolean getUseDeveloperSupport() {
      return BuildConfig.DEBUG;
    }

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
          new MainReactPackage()
      );
    }
  };

  @Override
  public ReactNativeHost getReactNativeHost() {
    return mReactNativeHost;
  }

  @Override
  public void onCreate() {
    super.onCreate();
    SoLoader.init(this, /* native exopackage */ false);
  }
}

我使用了react-native链接并告诉我react-native-push-notifications已被链接。这就是为什么我没有添加任何东西到java文件。我试图添加问题代码，然后debuger告诉我，javatojava的错误

请帮忙。

Answer 1

我可以看到包没有链接到你的java文件。

添加

import com.dieam.reactnativepushnotification.ReactNativePushNotificationPackage;

在MainApplication.java文件的第一个文件中，还将新的ReactNativePushNotificationPackage()添加到getPackages方法返回值，所以它看起来像这样：

 @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
          new MainReactPackage(),
              new ReactNativePushNotificationPackage()
      );
    }

https://github.com/zo0r/react-native-push-notification/issues/728

为我工作。

build.gradle中缺少编译项目（'：react-native-push-notification'）

react-native-push-notification未定义
