Question

我收到一个名为“没有这样的表”的错误。此错误以前没有。我正在使用Sugar ORM for SQLite Database。我尝试重新安装应用程序，但这不起作用。

Messages.class

import com.orm.SugarRecord;



public class Messages extends SugarRecord {
    String senderId;
    String receiverId;
    String message;


public Messages(){

}

public Messages(String senderId, String receiverId, String message) {
    this.message = message;
    this.senderId = senderId;
    this.receiverId = receiverId;
}

public void setMessage(String message) {
    this.message = message;
}
public void setSenderId(String senderId) {
    this.senderId = senderId;
}
public void setReceiverId(String receiverId) {
    this.receiverId = receiverId;
}


public String getMessage(){
    return message;
}
public String getSenderId(){
    return senderId;
}
public String getReceiverId() {
    return receiverId;
}

}

存储数据

public void send(View view) {
    channel.sendUserMessage(sendText.getText().toString(), new BaseChannel.SendUserMessageHandler() {
        @Override
        public void onSent(UserMessage userMessage, SendBirdException e) {
            if (e != null) {
                // Error.
                Log.d("Error", "MSG not sent");
                return;
            }
            Messages messages = new Messages(sender, receiver, userMessage.getMessage());
            messages.save();
            sentText.setText(sendText.getText().toString());
        }
    });
}

logcat的

您需要在SugarApp中指定AndroidManifest.xml作为您的应用类。您可以通过更改android:name代码的application属性来实现此目的。

请检查：Getting started with Sugar ORM

如果问题仍然存在，请尝试这些，

尝试禁用即时运行
尝试从AndroidManifest文件中删除这些行：

的AndroidManifest.xml

<meta-data android:name="DATABASE" android:value="sugar_chat.db" />
<meta-data android:name="VERSION" android:value="2" />
<meta-data android:name="QUERY_LOG" android:value="true" />
<meta-data android:name="DOMAIN_PACKAGE_NAME" android:value="loany.gmx.com.sendbirdchat" />
