Question

我想在移动设备启动时启动活动。当我从我的手机启动应用程序时它很好但是当我重新启动手机时活动没有启动。 LogCat中没有错误。我发布了我的完整代码，以便你们可以理解。

这是我的

主要活动

import android.app.Activity; import android.content.Intent; import android.net.Uri; import android.os.Bundle;

公共类MainActivity扩展了Activity {

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

    Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com/"));
    startActivity(browserIntent);
}

}

这是我的另一个班级

BootReciever

import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent;

公共类BootReciever扩展了BroadcastReceiver {

@Override
public void onReceive(final Context context, Intent intent) {
    // TODO Auto-generated method stub


    new Thread(new Runnable() {

        @Override
        public void run() {
            try {
                Thread.sleep(5000);
            } catch (InterruptedException e) {
            }

            Intent myIntent = new Intent(context, MainActivity.class);
            myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(myIntent);
        }
    }).start();

}

}

试试这个

@Override
public void onReceive(final Context context, Intent intent) {
    Intent myIntent = new Intent(context, MainActivity.class);
    myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(myIntent);
}

和

<uses-permission android:name="android.permission.VIBRATE" >
</uses-permission>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

<uses-sdk
    android:minSdkVersion="11"
    android:targetSdkVersion="21" />
<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <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>
    <receiver
        android:name="com.android.bitter.BootReciever"
        android:enabled="true"         >
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
            <action android:name="android.intent.action.QUICKBOOT_POWERON" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </receiver>
</application>

活动无法在手机启动，Android BroadcastReceiver上启动
