如何将我的应用程序设置为启动应用程序,因此当移动设备重新启动或打开时,我的应用程序将启动。
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.installedapps22"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="8" />
<application android:icon="@drawable/cherry_icon" android:label="@string/app_name">
<activity android:name=".MainActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".ListInstalledApps" > </activity>
<activity android:name=".TabsLayoutActivity" />
</application>
</manifest>
编辑以下是我更新的代码,但仍无效:
清单:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.installedapps22"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<application android:icon="@drawable/cherry_icon" android:label="@string/app_name">

android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:enabled="true" android:name="com.app.reciever.BootUpReciever">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />

</intent-filter>
</receiver>
<activity android:name=".ListInstalledApps" > </activity>

BroadcastReciever:
package com.example.installedapps22;
public class BootUpReciever extends BroadcastReceiver
{
@Override
public void onReceive(final Context context, Intent intent) {
Intent i = new Intent(context, MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}

这是将应用程序设置为设备中的启动应用程序创建类扩展BroadCast接收器
public class BootUpReciever extends BroadcastReceiver
{
@Override
public void onReceive(final Context context, Intent intent) {
Intent i = new Intent(context, ServerPreferenceActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}
添加清单文件的权限以访问启动接收器
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
注册扩展了manifest.xml中Broadcast receiver
的接收者
<receiver android:enabled="true" android:name="com.app.reciever.BootUpReciever">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>

首先在清单中使用权限
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
并在清单
中声明启动接收器<receiver android:name=".BootReciever">
<intent-filter >
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
用户接收器开始你的主动
public class BootReciever extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Intent myIntent = new Intent(context, MainActivity.class);
myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(myIntent);
}
}

对于您编辑的代码,请尝试替换以下内容:
android:name="com.app.reciever.BootUpReciever
使用:
android:name="com.example.installedapps22.BootUpReciever
