好了,为了让我的新的一页,前面我需要让睡一会...因此,新的code将是:
公共类MyPhoneBroadcastReceiver扩展的BroadcastReceiver {
公共无效的onReceive(最终上下文的背景下,意图意图){
螺纹pageTimer =新的Thread(){
公共无效的run(){
尝试{
睡眠(1000);
}赶上(InterruptedException异常E){
e.printStackTrace();
} 最后 {
意图I =新意图();
i.setClass(背景下,Call.class);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(ⅰ);
}
}
};
pageTimer.start();
}
}
但是 - 原来来电程序正在后台仍在运行...
有什么办法来替代它,而不是打开新的应用程序ontop呢?
谢谢!
I'm trying to make an new incoming call screen in android,
when i get an incoming call my app starts - but crashes immediately, and the default incoming call screen is coming up.
what am i doing wrong?
my code:
AndroidManifest.xml :
<?xml version="1.0" encoding="utf-8" ?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myfirstapp"
android:versionCode="7"
android:versionName="7">
<uses-sdk android:minSdkVersion="7" android:targetSdkVersion="10"></uses-sdk>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.MODIFY_PHONE_STATE"/>
<uses-permission android:name="android.permission.CALL_PHONE" />
<application android:label="@string/app_name" android:icon="@drawable/ic_launcher">
<receiver android:name=".MyPhoneBroadcastReceiver" android:enabled="true">
<intent-filter android:priority="99999">
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
<activity
android:name=".Call" >
</activity>
</application>
</manifest>
MyPhoneBroadcastReceiver.java:
package com.example.myfirstapp;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
public class MyPhoneBroadcastReceiver extends Activity{
public void onReceive(final Context context, Intent intent) {
Intent main_intent = new Intent(this, Call.class);
context.startActivity(main_intent);
}
}
Call.java:
package com.example.myfirstapp;
import android.app.Activity;
import android.os.Bundle;
public class Call extends Activity{
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
the log is:

Ok, in order to make my new page in the front i need to make it sleep for a while...so the new code will be:
public class MyPhoneBroadcastReceiver extends BroadcastReceiver{
public void onReceive(final Context context, Intent intent) {
Thread pageTimer = new Thread(){
public void run(){
try{
sleep(1000);
} catch (InterruptedException e){
e.printStackTrace();
} finally {
Intent i = new Intent();
i.setClass(context, Call.class);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}
};
pageTimer.start();
}
}
But - the original incoming call program is still running in the background...
Is there any way to replace it instead opening new app ontop of it?
Thanks!
