Android Auto Launch App ( Delphi 10.3.3 )

[robert83 2]

Hello everyone,

 

Does anyone know how to Auto Start an Application ( once it is launched 1x by user ) after Reboot on Android ?

 

I have found some example for Delphi XE5 but that is way to old .

 

I know that I have to set Receive boot Completed to true... but after that... how do I process this in the Program ?

 

Thank you.

Not tested myself, but you have a look here  or here (German DP)

Unfortunately it is not working . No Error but nothing starts.

 

Anyway I made "some" progress with some JAVA Code . But I am stuck.

 

Created following JAVA File :

 

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);
        }
     
}

Then I made a JAR file out of it like this :

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"

My AndroidManifest.template looks like this :

 

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

        <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.embarcadero.XLRBoot"
                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) -->

Now if I reboot I at least get an error and some information in the Log File, but I cannot figure out why is this not working :

Any ideas what I did wrong here?

 

Thank you.

Not enough time to look deeper into this., and what you are doing wiht Java and Delphi.

But from the error message

Quote

Didn't find class "com.embarcadero.XLRBoot" on path: DexPathList[

This could have something to do with the customizing of the classes.dex file.

That is a big change in the underlying Delphi stuff, so I'm not sure if you really need to use a custom classes.dex,

better to avoid that, if possible.

But your task sounds as if it might be needed.

 

To run a sticky service on boot could be an option too, but I haven't tested that yet.

I'm not sure if there were any options to allow auto-starting after boot, maybe so, with some hacks.

Unfortunately there were so many internals changed in Android, since those posts, so maybe also this doesn't work as described before.

I have solved it .

 

Step 1 :

create src\com\XLR folder in your App Directory

there create the file BootReceiver.java with the following content :

 

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);  
        }

}

Step 2 :

Under your App Directory create build.bat with following content :

 

@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

Step 3 :

now run build.bat and it will create the class and jar files in the Output Directory in your App Directory.

Step 4 :

Alter your AndroidManifest.template like this

<?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) -->

Step 5:

Add the output\jar\XLRBoot.jar file to your Libraries inside Delphi and Run the programm.

Step 6:

After Run the Program Starts, Stop it Start it again . Now Reboot it will start. Turn Device Off and Turn On again and it will start.

 

Thank you.

 

SPECIAL NOTE FOR ANDROID 10 :

You must set the Permissions System Alert window in Delphi. And on the Phone under App Info -> Advanced enable the Display over other apps settings.

@robert183

Thanks for the description.

As far as I know from older versions, with a custom classes.dex you cannot debug any more.

Is that still true for Rx1042, with your setup ?

 

[robert83 2]

@Rollo62

Hi , sorry it took a while , but I just continued development on this tool which requires auto start with the custom .dex

And debug is working!

 

I am using Delphi 10.3.3
