我需要启动 android 前台服务，并在设备启动时从该服务启动 Activity 。我广泛搜索了网络和 stackoverflow 并尝试了不同的建议，但很奇怪我无法使用此功能。
我不明白我做错了什么。
下面是我项目的代码和 list 文件的内容。
我做错了什么以及如何解决它，在大多数 Android 设备上工作的功能？
这是我的 AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="kor.location.tracker">
<uses-permission android:name="android.permission.INTERNET" ></uses-permission>
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<receiver android:name="kor.location.tracker.AutoStart">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<activity
android:name=".MainActivity"
android:label="@string/app_name"
android:theme="@style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:enabled="true"
android:name="kor.location.tracker.WorkerService"
android:exported="true"
android:permission="android.permission.BIND_JOB_SERVICE"
/>
</application>
</manifest>
这是我的 Austostart.java:
package kor.location.tracker;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Build;
import android.util.Log;
import android.widget.Toast;
public class AutoStart extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent arg1)
{
try {
System.out.println("test1");
if (Intent.ACTION_BOOT_COMPLETED.equals(arg1.getAction())) {
System.out.println("test2");
WorkerService.enqueueWork(context, new Intent());
System.out.println("test3");
}
}catch(Exception ex) {
Toast.makeText(context, ex.getMessage(), Toast.LENGTH_LONG).show();
}
/*
Intent intent = new Intent(context, WorkerService.class);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
context.startForegroundService(intent);
} else {
context.startService(intent);
}
Log.i("Autostart", "started");
*/
}
}
这是我的服务类 WorkerService.java:
package kor.location.tracker;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;

import android.util.Log;
import android.widget.Toast;
import androidx.annotation.NonNull;
import androidx.core.app.JobIntentService;
public class WorkerService extends JobIntentService
{
public static void enqueueWork(Context context, Intent work) {
enqueueWork(context, WorkerService.class, 104501, work);
}
/*
private static final String TAG = "MyService";
@Override
public IBinder onBind(Intent intent) {
return null;
}
public void onDestroy() {
Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show();
Log.d(TAG, "onDestroy");
}
*/
@Override
protected void onHandleWork(@NonNull Intent intent) {
Intent intents = new Intent(getBaseContext(),MainActivity.class);
intents.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intents);
//Toast.makeText(this, "My Service Started", Toast.LENGTH_LONG).show();
//Log.d(TAG, "onStart");
}
/*
@Override
public void onStart(Intent intent, int startid)
{
final LocationListener mLocationListener = new LocationListener() {
@Override
public void onLocationChanged(final Location location) {
//your code here
String kuku = location.getLatitude() + "=" + location.getLongitude();
Toast.makeText(WorkerService.this, kuku, Toast.LENGTH_LONG).show();
Log.d(TAG, kuku);
;
;
location.getAltitude();
location.getSpeed();
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
@Override
public void onProviderEnabled(String provider) {
}
@Override
public void onProviderDisabled(String provider) {
}
};
LocationManager mLocationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
try {
mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 60000,
1, mLocationListener);
}catch (SecurityException ex){
Toast.makeText(this, ex.getMessage(), Toast.LENGTH_LONG).show();
Log.d(TAG, ex.getMessage());
}
Intent intents = new Intent(getBaseContext(),MainActivity.class);
intents.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intents);
Toast.makeText(this, "My Service Started", Toast.LENGTH_LONG).show();
Log.d(TAG, "onStart");
}
*/
}
这是我尚未启动的 Activity :

super.onCreate(savedInstanceState);

setSupportActionBar(toolbar);
FloatingActionButton fab = findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
Toast.makeText(getBaseContext(), "Hello........", Toast.LENGTH_LONG).show();
List<String> permissions = new ArrayList<String>();
if(getApplicationContext().checkCallingOrSelfPermission(Manifest.permission.INTERNET) != PackageManager.PERMISSION_GRANTED){
permissions.add(Manifest.permission.INTERNET);
}
if(getApplicationContext().checkCallingOrSelfPermission(Manifest.permission.RECEIVE_BOOT_COMPLETED) != PackageManager.PERMISSION_GRANTED){
permissions.add(Manifest.permission.RECEIVE_BOOT_COMPLETED);
}

permissions.add(Manifest.permission.FOREGROUND_SERVICE);
}
if(permissions.size()>0) {
String[] arr = new String[permissions.size()];
permissions.toArray(arr);
//System.out.println();
ActivityCompat.requestPermissions(this, arr, 1);
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {

int id = item.getItemId();
//noinspection SimplifiableIfStatement

return true;
}
return super.onOptionsItemSelected(item);
}
}
最佳答案
1- 对于从后台启动 Activity 的问题
在 API29 Android 限制中，从后台启动 Activity 。前台服务也被视为后台进程。如果您在 Android 10 中进行测试，您的 Activity 可能会受到此限制的影响。
Android Q 限制:https://developer.android.com/guide/components/activities/background-starts
可能的解决方案: https://stackoverflow.com/a/59421118/11982611
2- 某些品牌限制应用程序在开机时启动，以缩短设备的启动时间。因此应用程序需要独占权限才能在开机时启动。
