Tutorial How to add a popup toast message in game startup

[Mika Cybertron]

[Requirements]
0. A working brain
1. A Computer
2. The apk file, obviously
3. dex/Apk decompiler with xml decoding support eg.(Apktool)
4. Text editor (Notepad++, Sublime Text, Atom, notepad)

[Info]
What exactly are we trying to do?

Spoiler: IMAGE

*see image* Pretty much looks like that, but you may notice some moded games here show up with custom text like "diHacked oleh Aku sayang", "Hacked by Me" etc.

[Body]
1. Decompile apk with tools that mentioned above
2. Open AndroidManifest.xml, look for <action android:name="android.intent.action.MAIN"/>

<activity android:configChanges="locale|fontScale|keyboard|keyboardHidden|mcc|mnc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|touchscreen|uiMode" android:label="@string/app_name" android:launchMode="singleTop" android:name="net.circleous.domtweaks.StartActivity" android:screenOrientation="landscape">
  <intent-filter>
    <action android:name="android.intent.action.MAIN"/>
    <category android:name="android.intent.category.LAUNCHER"/>
  </intent-filter>
</activity>

if you read that carefully and see on top of it(<action android:name="android.intent.action.MAIN"/>) -> android.name="net.circleous.domtweaks.StartActivity"
You have to find StartActivity.smali file at smali/net/circleous/domtweaks/
3. If you found the StartActivity.smali file, open it.
4. Search the word "onCreate" it'il be look like this.

.method protected onCreate(Landroid/os/Bundle;)V
.locals

5. Add this under .locals

const/4 v0, 0x1

const-string v1, "YOUR MESSAGE HERE"

invoke-static {p0, v1, v0}, Landroid/widget/Toast;->makeText(Landroid/content/Context;Ljava/lang/CharSequence;I)Landroid/widget/Toast;

move-result-object v0

invoke-virtual {v0}, Landroid/widget/Toast;->show()V

#OTHER CODE THAT YOU MAY NOT TOUCH IT

6. If you notice in line 2

const-string v1, "YOUR MESSAGE"

Change "YOUR MESSAGE" to everything what you want.
Example:

const/4 v0, 0x1

const-string v1, "Platinmods.com"

invoke-static {p0, v1, v0}, Landroid/widget/Toast;->makeText(Landroid/content/Context;Ljava/lang/CharSequence;I)Landroid/widget/Toast;

move-result-object v0

invoke-virtual {v0}, Landroid/widget/Toast;->show()V

7. Recompile, sign and install the apk

A question. Sometimes i added this Code under locals and recompile, the Game forceclosed. I have 3 Games it Works and other Games it dosn't work. What's wrong? Its the correct smali and i copied the Code direct without a enter(empty Line).

This is already the most easiest way to make a toast message buddy.

And when the file is encoded?

And when the file is encoded?

You need to decompile the apk buddy.
But it's not needed to do that, because APK Easy Tool shows your everytime the right Activity, just drag and drop the apk into APK Easy Tool

There was no success because these 2 boxes were checked! For it to work it disables
Thanks again for the support

So what if it doesn't have android.name="XXX.XXX.XXXXXX.StartActivity" ?

<application android:allowBackup="true" android:appComponentFactory="androidx.core.app.CoreComponentFactory" android:icon="@mipmap/app_icon" android:label="@string/app_name" android:theme="@style/UnityThemeSelector">
<meta-data android:name="android.max_aspect" android:value="1.86"/>
<activity android:configChanges="density|fontScale|keyboard|keyboardHidden|layoutDirection|locale|mcc|mnc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|touchscreen|uiMode" android:hardwareAccelerated="false" android:label="@string/app_name" android:launchMode="singleTask" android:maxAspectRatio="1.86" android:name="com.unity3d.player.UnityPlayerActivity" android:resizeableActivity="false" android:screenOrientation="sensorLandscape">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>

Already tried in the smali folder for android:name="com.unity3d.player.UnityPlayerActivity" and made the game crash
