Setelah berhasil membuat Aplikasi untuk Memanggil Intent untuk Memilih (Browse File) dengan Intent. Kali ini kita pelajari cara lebih lanjut untuk memanggil Kamera Intent (Open Camera, Save Picture, Choose Photo) menggunakan Intent. Ada 4 Cara yang kita coba disini.

Program utama kita letakkan di MainActivity

MainActivity.java

package com.amijaya.androidcameraintent;

import java.io.File;

import java.io.FileOutputStream;
import java.io.IOException;

import android.graphics.Bitmap;
import android.net.Uri;

public static File imgfile;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);


TextView01 = (TextView) findViewById(R.id.TextView01);
TextView02 = (TextView) findViewById(R.id.TextView02);
ImageView01 = (ImageView) findViewById(R.id.ImageView01);
Button01 = (Button) findViewById(R.id.Button01);

Button01.setOnClickListener(new OnClickListener() {

}

public String getRealPathFromURI(Uri contentUri) {

private File getTempFile(Context context) {
// it will return /sdcard/image.tmp
File path = new File(Environment.getExternalStorageDirectory(), context
.getPackageName());
if (!path.exists()) {
path.mkdir();
}
return new File(path, "image.tmp");
}

}

Kemudian tampilannya kita pakai saja tampilan default kemudian ditambah empat buah Button dengan nama Button01, Button02, Button03, Button04 dan dua buah TextView dengan nama TextView01, TextView02 dan satu buah ImageView dengan nama ImageView01 :

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    />
<Button android:text="Kamera" android:id="@+id/Button01" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
<Button android:text="Kamera" android:id="@+id/Button02" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
<Button android:text="Kamera" android:id="@+id/Button03" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
<Button android:text="Kamera" android:id="@+id/Button04" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
<TextView android:text="" android:id="@+id/TextView01" android:layout_width="wrap_content" android:layout_height="wrap_content"></TextView>
<TextView android:text="" android:id="@+id/TextView02" android:layout_width="wrap_content" android:layout_height="wrap_content"></TextView>
<ImageView android:id="@+id/ImageView01" android:layout_width="wrap_content" android:layout_height="wrap_content"></ImageView>
</LinearLayout>

Android Manifest perlu ditambahkan permisson untuk menggunakan Camera dan permission Baca Tulis ke SDCARD.

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.amijaya.androidcameraintent"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".MainActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

    </application>
    <uses-sdk android:minSdkVersion="8" />
 <uses-permission android:name="android.permission.CAMERA" />
 <uses-feature android:name="android.hardware.camera" />
 <uses-feature android:name="android.hardware.camera.autofocus" />
 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
</manifest>
