当有人从应用商店安装我的应用时，打开按钮（通常在安装完成后位于卸载按钮旁边）显示为灰色，并且在他们的应用抽屉中找不到该应用。

此外，当我从 Eclipse 执行选择默认活动时，它在控制台中说它安装了 APK，但它没有启动。如果我在运行配置中选择 Splash 活动作为默认活动，它会顺利运行，但之后我仍然无法在我的应用程序抽屉中找到它。帮助将不胜感激c：

显现： 

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="17" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.meteorfiber.gangnamstyle.Splash"
        android:configChanges="keyboardHidden|orientation|screenSize"
        android:label="@string/app_name"
        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" >
        <intent-filter>
            <action android:name="com.meteorfiber.gangnamstyle.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="com.meteorfiber.gangnamstyle.MainActivity"
        android:configChanges="keyboardHidden|orientation|screenSize"
        android:label="@string/app_name"
        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" >
        <intent-filter>
            <action android:name="com.meteorfiber.gangnamstyle.MAINACTIVITY" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
</application>

</manifest>

溅：

package com.meteorfiber.gangnamstyle;

import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.os.Handler;
import android.preference.PreferenceManager;

public class Splash extends Activity {

private final int SPLASH_DISPLAY_LENGTH = 3000;

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

@Override
protected void onResume() {
    super.onResume();
    SharedPreferences sp = PreferenceManager
            .getDefaultSharedPreferences(this);

    boolean isSplashEnabled = sp.getBoolean("isSplashEnabled", true);

    if (isSplashEnabled) {
        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {

                Splash.this.finish();

                Intent mainIntent = new Intent(Splash.this,
                        MainActivity.class);
                Splash.this.startActivity(mainIntent);
            }
        }, SPLASH_DISPLAY_LENGTH);
    } else {

        finish();
        Intent mainIntent = new Intent(Splash.this, MainActivity.class);
        Splash.this.startActivity(mainIntent);
    }
}
 }

主要活动：

package com.meteorfiber.gangnamstyle;


import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.Window;
import android.view.WindowManager;

public class MainActivity extends Activity {

    MediaPlayer ourSong;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(new GameView(this));
    ourSong = MediaPlayer.create(MainActivity.this, R.raw.song);
    ourSong.start();
}

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK) {
        // preventing default implementation previous to
        // android.os.Build.VERSION_CODES.ECLAIR
        return true;
    }
    return super.onKeyDown(keyCode, event);
}

@Override
protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    ourSong.release();
}

}

将您的起始活动的意图过滤器更改为

<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

android 启动器与设置活动一起尝试在您的应用程序中找到此意图过滤器以启动活动。如果找不到，您的活动将无法使用典型的启动器启动，并且不会显示。
