我的 Manifest.xml 文件中有这个：

我的 StartOnBoot.java 文件中有这个：

编辑：这是我拥有的实际 StartOnBoot.java 文件：

package com.tominocz.stonequestapp;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;

@SuppressWarnings("deprecation")
@SuppressLint("SdCardPath")
public class StartOnBoot extends BroadcastReceiver {

    public static String Latest;
    public static String previous;

    @Override
    public void onReceive(final Context context, final Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
            if (new File("/data/data/com.tominocz.stonequestapp/app.properties").exists()) {
                Config.load();

                if (MainActivity.StartOnBoot = true) {
                    getLatestVersion(context);
                    if (MainActivity.EnableNotifications = true) {
                        triggerUpdateNotification(context, "New version " + Latest + " released!");
                    }
                }
            }
        }
    }

    public static void getLatestVersion(Context ctx) {
        try {
            String myUri = "http://www.stonequest.de/version.php";
            HttpClient httpClient = new DefaultHttpClient();
            HttpGet get = new HttpGet(myUri);

            HttpResponse response = httpClient.execute(get);

            String ver = EntityUtils.toString(response.getEntity(), "UTF-8");
            if (ver != null) {
                Latest = ver;
                if (MainActivity.EnableNotifications = true) {
                    if (previous != Latest) {
                        triggerUpdateNotification(ctx, "New version " + Latest + " released!");
                    }
                }
            }
        } catch (Exception e) {

        }
    }

    public static void loadLastVersion() {
        try {
            FileInputStream fis = new FileInputStream(new File("/data/data/com.tominocz.stonequestapp/Last.ver"));
            BufferedReader br = new BufferedReader(new InputStreamReader(fis));
            previous = br.readLine();
            fis.close();
            br.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private static void triggerUpdateNotification(Context ctx, String s) {
        CharSequence title = "StoneQuest just got updated!";
        CharSequence message = s;
        NotificationManager notificationManager;
        notificationManager = (NotificationManager) ctx.getSystemService("notification");
        Notification notification;
        notification = new Notification(com.tominocz.stonequestapp.R.drawable.ic_launcher, "New version released!",
                System.currentTimeMillis());
        PendingIntent pendingIntent = PendingIntent.getActivity(ctx, 0, null, 0);
        notification.setLatestEventInfo(ctx, title, message, pendingIntent);
        notificationManager.notify(1010, notification);
    }
}

我不知道我的应用程序是否这样做，但每当 Android 设备启动时，都会显示一条通知说应用程序权限被拒绝或类似的东西..

不管有没有，问题是应用程序不会在启动时启动。

我想知道为什么..

有人知道为什么吗？谢谢。

【问题讨论】：

尝试将 android.intent.action.MAIN 替换为 com.tominocz.stonequestapp.MainActivity 并将 android.intent.category.LAUNCHER 替换为 android.intent.category.DEFAULT，发布您的 logcat 以获得许多建议
哦，等等，我想我知道这里出了什么问题。也许在 StartOnBoot.java 文件中，我应该删除 if 语句并扫描系统是否已完成启动。
StartOnBoot.java 应该是普通的类文件然后......就像没有扩展的东西......
我没有发布整个代码，因为原始代码不是用于启动应用程序..
然后把 logcat 和 MainActivity 扩展 Acvtivty 对吗？您是否尝试过我所说的替换？

试试这个。

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

        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"

            <intent-filter>
                <action android:name="com.tominocz.stonequestapp.MAINACTIVITY" />

                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>
        <activity
            android:name=".PlayerListActivity"
            android:launchMode="singleTask"
            android:screenOrientation="nosensor"
            android:theme="@style/AppTheme" >
            <intent-filter>
                <action android:name="com.tominocz.stonequestapp.PLAYERLISTACTIVITY" />
                <action android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>
        <activity
            android:name=".SettingsActivity"
            android:launchMode="singleTask"
            android:screenOrientation="nosensor"
            android:theme="@style/AppTheme" >
            <intent-filter>
                <action android:name="com.tominocz.stonequestapp.SETTINGSACTIVITY" />
                <action android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>
    </application>

</manifest>

将此添加到 onReceive()

  Intent start = new Intent(getApplicationContext(), MainActivity.class);
  startActivity(start);

并确保 MainActivity 扩展 Activity
