Delphi 10.3.3, Android App AutoStart on Boot (Android 8.x, 10.x)

Question

我创建了一个 java 文件，其内容如下：

package com.embarcadero.XLRBoot;
     
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Intent;
import android.content.Context;
     
public class startup extends BroadcastReceiver
{
     
    @Override
        public void onReceive(Context context, Intent intent) 
        {
               Intent sintent = new Intent();
           sintent.setClassName(context, "com.embarcadero.firemonkey.FMXNativeActivity");
               sintent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
               context.startActivity(sintent);
        }
     
}

我创建了一个 JAR 文件，如下所示：

C:\Program Files (x86)\Java\jdk1.7.0_71\bin>jar cf com-embarcadero-XLRBoot.jar "d:\Delphi XE 10\XLR Spider\Boot Receiver\com-embarcadero-XLRBoot.java"

我的 AndroidManifest.template 看起来像这样：

<?xml version="1.0" encoding="utf-8"?>
<!-- BEGIN_INCLUDE(manifest) -->

            <meta-data android:name="android.app.lib_name"
                android:value="%libNameValue%" />
            <intent-filter>

                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </receiver>
        <!-- Registration is complete -->    
        <%activity%>
        <%receivers%>
    </application>
</manifest>
<!-- END_INCLUDE(manifest) -->

我在 Delphi 中设置了以下权限：[x] 接收启动已完成 [x] 重新排序任务

我编译我的应用程序，运行它，停止它，重新启动设备。 我收到一个错误，它停止了。

在日志中，我看到以下条目：

我显然错过了一些东西，但是什么？

感谢您的帮助。

更新 4

我删除了以前的更新，因为我有点偏离。 所以这就是我需要正确创建文件的方式。

生成 Class 文件

javac -Xlint:all -classpath "c:\Users\Public\Documents\Embarcadero\Studio\20.0\PlatformSDKs\android-sdk-windows\platforms\android-26\android.jar" "d:\Delphi XE 10\XLR Spider\Boot Receiver\0.2\startup\com\embarcadero\XLRBoot\startup.java" -d "d:\Delphi XE 10\XLR Spider\Boot Receiver\0.2\startup"

生成 JAR 文件：

jar cf "d:\Delphi XE 10\XLR Spider\Boot Receiver\0.2\startup\com\embarcadero\XLRBoot\startup.jar" -C "d:\Delphi XE 10\XLR Spider\Boot Receiver\0.2\startup\com\embarcadero\XLRBoot" startup.class

Delphi 给出 EXEC(1) 执行错误。

Answer 1

步骤1：

在您的 App Directory 中创建 src\com\XLR 文件夹

在那里创建具有以下内容的文件 BootReceiver.java：

package com.XLR;

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

public class BootReceiver extends BroadcastReceiver
{

        @Override
        public void onReceive(Context context, Intent intent) 
        {
           Intent launchintent = new Intent();
           launchintent.setClassName(context, "com.embarcadero.firemonkey.FMXNativeActivity");           
           launchintent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
           context.startActivity(launchintent);  
        }

}

第2步：

在您的 App Directory 下创建 build.bat 并包含以下内容：

@echo off
echo.
echo Compiles your Java code into classes.dex
echo Verified to work in Delphi 10.3.3
echo.
echo Place this batch in a java folder below your project (project\java)
echo Place the source in project\java\src\com\dannywind\delphi
echo If your source file location or name is different, please modify it below.
echo.

setlocal

set ANDROID_JAR="C:\Users\Public\Documents\Embarcadero\Studio\20.0\PlatformSDKs\android-sdk-windows\platforms\android-26\android.jar"
set DX_LIB="C:\Users\Public\Documents\Embarcadero\Studio\20.0\PlatformSDKs\android-sdk-windows\build-tools\28.0.2\lib"
set EMBO_DEX="D:\PRG\20.0\lib\android\debug\classes.dex"
set PROJ_DIR=%CD%
set VERBOSE=0
set JAVASDK="C:\Program Files (x86)\Java\jdk1.7.0_71\bin"
set DX_BAT="C:\Users\Public\Documents\Embarcadero\Studio\20.0\PlatformSDKs\android-sdk-windows\build-tools\28.0.2\dx.bat"

echo.
echo Compiling the Java source files
echo.
pause
mkdir output 2> nul
mkdir output\classes 2> nul
if x%VERBOSE% == x1 SET VERBOSE_FLAG=-verbose
%JAVASDK%\javac %VERBOSE_FLAG% -Xlint:all -classpath %ANDROID_JAR% -d output\classes -source 1.6 -target 1.6 src\com\XLR\BootReceiver.java

echo.
echo Creating jar containing the new classes
echo.
pause
mkdir output\jar 2> nul
if x%VERBOSE% == x1 SET VERBOSE_FLAG=v
%JAVASDK%\jar c%VERBOSE_FLAG%f output\jar\XLRBoot.jar -C output\classes com


:Exit

endlocal

第 3 步：

现在运行 build.bat，它将在您的应用程序目录的 Output 目录中创建 class 和 jar 文件。

第4步：

像这样更改您的 AndroidManifest.template

<?xml version="1.0" encoding="utf-8"?>
<!-- BEGIN_INCLUDE(manifest) -->
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="%package%"
        android:versionCode="%versionCode%"
        android:versionName="%versionName%"
        android:installLocation="%installLocation%">

    <uses-sdk android:minSdkVersion="%minSdkVersion%" android:targetSdkVersion="%targetSdkVersion%" />
    <%uses-permission%>
    <uses-feature android:glEsVersion="0x00020000" android:required="True"/>
    <application android:persistent="%persistent%" 
        android:restoreAnyVersion="%restoreAnyVersion%" 
        android:label="%label%" 
        android:debuggable="%debuggable%" 
        android:largeHeap="%largeHeap%"
        android:icon="%icon%"
        android:theme="%theme%"
        android:hardwareAccelerated="%hardwareAccelerated%"
        android:resizeableActivity="false">

        <%provider%>
        <%application-meta-data%>
        <%uses-libraries%>
        <%services%>
        <!-- Our activity is a subclass of the built-in NativeActivity framework class.
             This will take care of integrating with our NDK code. -->
        <activity android:name="com.embarcadero.firemonkey.FMXNativeActivity"
                android:label="%activityLabel%"
                android:configChanges="orientation|keyboard|keyboardHidden|screenSize"
                android:launchMode="singleTask">
            <!-- Tell NativeActivity the name of our .so -->
            <meta-data android:name="android.app.lib_name"
                android:value="%libNameValue%" />
            <intent-filter>  
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter> 
        </activity>
        <receiver android:name="com.embarcadero.firemonkey.notifications.FMXNotificationAlarm" />
        <receiver android:name="com.XLR.BootReceiver"
                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>
        <!-- Registration is complete -->    
        <%activity%>
        <%receivers%>
    </application>
</manifest>
<!-- END_INCLUDE(manifest) -->

第 5 步：

将 output\jar\XLRBoot.jar 文件添加到 Delphi 内的库中并运行程序。

第 6 步：

运行程序启动后，停止它再次启动它。 现在重新启动它将启动。 关闭设备并再次打开，它将启动。

谢谢你。

ANDROID 10 的特别说明：

您必须在 Delphi 中设置权限系统警报 window。 在手机上的 App Info -> Advanced 下启用 Display over other apps 设置。
