Code Code Menggambar pada Canvas
1. ctx.fillRect(x,y,1,1);
menggambar titik 1px
2. ctx.beginPath()
untuk memulai/ membuat garis baru.
3. ctx.moveTo(x,y)
untuk menentukan titik awal
4. ctx.lineTo(x,y)
untuk menentukan titik akhir
5. ctx.stroke()
untuk menggambar garisnya.
6. ctx.strokeRect(x,y,w,h)
persegi dengan garis (outline) saja.
7. ctx.fillRect(x,y,w,h)
persegi dengan polesan warna (default-nya hitam).
8. ctx.clearRect(x,y,w,h)
persegi transparan untuk menghapus.
Seperti biasa, kita harus memberikan titik koordinat x dan y. Sementara nilai w dan h untuk lebar dan tingginya.
9. ctx.closePath()
untuk menggambar garis dari titik terakhir ke titik awal secara otomatis.
10. strokeText("text",x,y)
untuk teks dengan garis luar (outline) saja.
11. fillText("text",x,y)
untuk teks dengan warna (default hitam).
12. ctx.font = "64px Arial";
Jenis dan ukuran font
13. drawImage(img, x, y);
Menambahkan gambar
14. var image= new Image();
image.src="./bird.png";
ctx.drawImage(image,10,10,200,200);

Cara Import Library (firebase)
1. bikin project baru kemudian edit file build.gradle pertama dan tambahkan classpath untuk firebase
sperti ini
classpath 'com.google.gms:google-services:3.2.0' // google-services plugin
kemudian tambahkan maven dibawah jcenter() sperti ini
allprojects {
repositories {
jcenter()
maven {
url "https://maven.google.com" // Google's Maven repository
}
}
}
2. setelah itu edit file build.gradle yang kedua (module)
tambahkan compile untuk firebase didalam dependencies
dan letakan aplly plugin di paling bawah
apply plugin: 'com.google.gms.google-services'
3. terahir tambahkan library firebase.jar kedalam folder libs
buat folder baru (libs) di dalam folder yang ada folder src dan java
4.klik dan tahan file firebase.jar nya lalu klik add to projek nanti otomatis akan muncul dialog untuk mendowload maven library
selesai
nb: jika download maven library tidak muncul bisa library di dependencies dan di firebase.jar tidak sama versinya
Kedua
coba tutup IDENYA atau pindah projek kemudian buka kembali projek yang tadi nanti akan muncul maven download library

2.bikin file php dengan script sperti ini
<?php
//mengambil data di data.json
$file=file_get_contents("data.json");
$ambil= json_decode($file, true);
//menampilkan data
echo $ambil["nama"]."<br>";
echo $ambil["umur"];

untuk bisa berpindah anda harus mengetahui nama package aplikasi target dan activitynya
Seperti contoh di bawah
com.melki adalah package
Dan MainActivity adalah Activitynya
Tapi disini activitynya ditulis package + activity =com.melki.MainActivity

Dialog Native
Ingin suatu halaman aplikasi muncul tapi dengan model dialog ?
Dan bisa muncul dimana saja alias muncul diluar aplikasi
Anda hanya perlu menambahkan code ini
android:launchMode="singleInstance" android:excludeFromRecents="true"android:theme="@android:style/Theme.Dialog"
Kedalam AndroidManifest.xml <activity>
Dan untuk mengatur ukuran dialog anda hanya perlu memberi ukuran yang tadinya wrap_content menjadi 500dip (contoh)
[DROID] Dialog Diluar Aplikasi
<html>
<button type="button" id="autoKlik" onclick="alert('Auto Klik Aktif setiap 50 detik')">Submit</button>
<script>
var button=document.getElementById("autoKlik");
setInterval(function(){
button.click();
}, 50000);
</script>
</html>
[WEB] membuat tombol klik otomatis setiap detik
Untuk mematikan fungsi tombol kembali anda hanya perlu menambahkan coding ini

}

moveTaskToBack(true);

cara menggunakan perbandingan di string yaitu menggunakan equals()
sperti beriku:

a="nilai pertama";
b="nilai kedua";
if(a.equals(b)){lakukan sesuatu}
