我需要在设备启动时运行我的应用程序。我尝试了以下代码。我的问题是,当我运行我的应用程序一次并且重新启动我的设备意味着它可以工作,如果我关闭我的设备然后打开意味着自动运行不会作品。为什么会这样?
MainActivity.java
public class MainActivity extends Activity {
ImageView mImageView;
Button swap_btn;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mImageView = (ImageView) findViewById(R.id.imageView1);
swap_btn = (Button) findViewById(R.id.button1);
mImageView.setImageResource(R.drawable.image_01);
swap_btn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
mImageView.setImageResource(R.drawable.image_02);
}
});
}
}
OpenOurAppReceiver.java
public class OpenOurAppReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Intent i = new Intent(context, MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}
的Manifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.bootup_sample_app"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver
android:name=".OpenOurAppReceiver"
android:enabled="true"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
</application>
</manifest>

如果您有一个在设备开机时应该可见的用户界面,请将其设为主屏幕。
