Android Speedometer

Pada kesempatan kali ini akan saya jelaskan cara membuat speedometer analog. Untuk membuat aplikasi ini, akan digunakan library dari cardiomood. Untuk pengguna eclipse, library tersebut dapat diunduh disini (link ini merupakan hasil convert yang dilakukan oleh penulis).

  1. Buat project android.
  2. Pada layout.xml, tambahkan program berikut:
    <com.cardiomood.android.speedometer.SpeedometerView
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    android:padding="8dp"
    android:id="@+id/speedometer" />
  3. Pada bagian activity, tambahkan program berikut:
    // Customize SpeedometerView
    SpeedometerView speedometer = (SpeedometerView) findViewById(R.id.speedometer);
    
    // Add label converter
    speedometer.setLabelConverter(new SpeedometerView.LabelConverter() {
         @Override
         public String getLabelFor(double progress, double maxProgress) {
             return String.valueOf((int) Math.round(progress));
         }
    });
            
    // configure value range and ticks
    speedometer.setMaxSpeed(300);
    speedometer.setMajorTickStep(30);
    speedometer.setMinorTicks(2);
    
    // Configure value range colors
    speedometer.addColoredRange(30, 140, Color.GREEN);
    speedometer.addColoredRange(140, 180, Color.YELLOW);
    speedometer.addColoredRange(180, 400, Color.RED);
            
    // Update value
    speedometer.setSpeed(100);
  4. Jalankan program.

Android NDK

Berikut adalah salah satu cara menggunakan Android NDK:

  1. Buat program Java.
  2. Buat program C/C++.
  3. Generate header.
    Contoh:

    javah -o HalloJNI.h -jni -classpath ../src com.example.hallojni.TestJNI

    HalloJNI.h -> File  hasil generate.
    com.example.hallojni.TestJNI -> class TestJNI.java

  4. Include header file pada program C/C++;
  5. Jalankan program.

Solusi:

  1. Pastikan nama class sama.
  2. Pastikan header file sudah di include.

LinkedHashMap

Mirip seperti HashMap, tetapi dengan pengorderan data sesuai dengan urutan elemen yang didaftarkan (insertion-order).

Contoh:

LinkedHashMap<Integer, String> mapAngka = new LinkedHashMap<Integer, String>();
mapAngka.put(1, "SATU");
mapAngka.put(2, "DUA");
mapAngka.put(3, "TIGA");
mapAngka.put(4, "EMPAT");
mapAngka.put(5,"LIMA");
System.out.println(mapAngka);

Hasil yang didapat:

{1=SATU, 2=DUA, 3=TIGA, 4=EMPAT, 5=LIMA}

Hard Drive Master Boot Record   Recently updated !

The MBR (Master Boot Record) is the first sector of a hard drive. It contains the boot loader code and the MPT (Master Partition Table). USB flash drives may also feature an MBR. If formatted as a hard drive they contain both an MBR and a boot record, if as a floppy, just a boot record.

The startup sequence
The motherboard completes a POST (power on self test) then the BIOS copies the MBR of the drive to memory location 7C00h (31744 decimal). It is then executed by a jump to it with the CPU instruction: JMP 0000:7C00
The MBR code then first copies itself to location 0600h (1536 decimal) and continues execution with a jump to location 061Dh.
The relocation is necessary as the code next checks the partition table (64 bytes near the end of the MBR) for the first partition that is marked active, the first sector of which is then copied to location 7C00h and executed.
If no bootable partition is found or the partition marked active does not contain an operating system, an error message is displayed using INT 10.

Types of MBR
The MBR may be of one of the several standard versions or a customization. The above description is for the MBR of a hard drive initialized with the DOS and Windows 95(A) FDISK. It requires that the first sector of the active partition must be at or under cylinder 1024 as the standard INT 13h Read function is used to copy that sector to location 7C00h (the INT 13h BIOS interrupt limits cylinders to 0 to 1023, sectors to 1 to 63 and heads 1 to 15, 8455716864 bytes, 8.4 GB).

The most common is the MBR used by Windows 98 and ME. It closely resembles the above except that an extended instruction is used to copy the first sector of the active partion to avoid the cylinder 1024 limitation.
The first two bytes usually indicate the MBR version:

FA 33 .. DOS 3.3 to Windows 95A
33 C0 .. Windows 95B, 98, 98SE, ME, 2000, XP, Vista
FA EB .. Linux LILO
EB 3C .. Windows Floppy Disk boot record
The FA instruction is disable interrupts, 33 C0 is XOR AX,AX

The first sector of the active partion is actually sector 63 of the partition as the first sector contains a redundant copy of the MBR and sectors 2 through 62 are normally empty (the remainder of the first cylinder). From Windows Vista, Microsoft installations place the first partition at absolute sector 2048 (2048 * 512 = 1,048,576 bytes).
Note that some anti virus or disk utility software make use of empty sectors.

Master Partition Table
The second part of the Master Boot Record, the MPT consists of 48 bytes, sixteen for each possible partition. The first byte indicates whether it is a bootable partition. A value of 80h represents true, a zero false. The next three bytes hold the cylinder, head and sector (CHS) of the boot sector. The fifth byte is the system:
0 .. Unused
1 .. DOS primary with 12 bit FAT
4 .. DOS primary with 16 bit FAT
5 .. DOS extended
6 .. DOS huge (more than 32MB)
The next three bytes hold the cylinder, head and sector (CHS) of the end of the partition.
The final two blocks of 4 bytes hold the number of sectors on the disk before the start of the partition (usually 63) and the number of sectors in the partition.

Note that the final two bytes of the MBR are always 55 and AA. The BIOS checks for them and if not present displays the error message DRIVE NOT READY.

The partition table is required to be operating system independent as it is loaded by the BIOS. The first sector of the active partion (the ‘boot sector’) which is subsequently copied to location 7C00h and executed, is part of the installed operating system.

Partition limits

DOS 3.31 .. 32MB
Windows 95A .. 2GB
Windows NT .. 4GB (installs to a FAT16 partition then converts it to NTFS)
Windows XP .. 137GB (SP2 extends)
The FAT 32 file system (introduced Windows 95 OSR2, Windows 2000 onwards) had a limit of 137.5 GB. Windows ME extended it to 2 terabytes (Windows 2000 and Windows XP will only format it to 32GB).
The NTFS file system is 2TB (32 bit) or 16 exabytes (64 bit).

Low level format
A hard drive has a low level format at time of manufacture. There are utilities available from the manufacturers web sites for such, however it is unlikely that they would be necessary as they just request the controller to place a physical format pattern on the disk.
Drives may contain a diagnostic cylinder (part of the IBM specification, customer engineering cylinder) in order to conduct tests without affecting stored data. It is the cylinder closest to the spindle.
Finally there may also be a secret cylinder used by the controller to record information.

IBM(Hitachi) .. http://www.hgst.com/hdd/support/download.htm

Fujitsu .. http://www.fel.fujitsu.com/home/drivers.asp?L=en&CID=1
Samsung .. http://www.samsung.com/Products/HardDiskDrive/utilities/index.htm

High level format
A boot record is placed on the drive when it is formatted. It holds the names of the system files that are required if the drive is to be bootable. The files may be added later with the SYS command if the drive was not originally formatted as bootable. The three required files are the two hidden files IO.SYS and MSDOS.SYS and the command interpreter COMMAND.COM

The Windows Format initializes four areas, the boot sector, the file allocation tables (FATs), the root directory and the data area. The boot sector consists of a JMP instruction then a data area followed by the actual boot code. The sector once again ends with 55 and AA.

How to make a USB drive bootable
Use Microsoft’s DiskPart command line utility (Windows XP, Vista, 7)
Open an elevated Command Prompt and run DISKPART then type LIST DISK.
Note the USB drive number (substitute for X below) then (backup any data first):

SELECT DISK X
CLEAN
CREATE PARTITION PRIMARY
SELECT PARTITION 1
ACTIVE
FORMAT FS=NTFS
ASSIGN

To exit from DiskPart type EXIT
Finally place the Windows DVD in a drive and navigate to the boot folder:

CD BOOT
BOOTSECT.EXE /nt60 X:

The master boot record on USB drives may easily be damaged. Microsoft provide a free command line tool, Sector Inspector (SecInspect.ext) for backup and restore. It is available here

Microsoft Sector Inspect tool use

To backup the MBR of the USB drive D: to a file backup.dsk:
secinspect.exe -backup d: c:\backup.dsk 0 1

To restore:
secinspect.exe -restore d: c:\backup.dsk 0 confirm

Details

The tool may also be used without any parameters to display a summary of all drives on the system. The following is for a Lexar 2GB drive:

Mengembalikan grub yang hilang menggunakan terminal commands   Recently updated !

Pad artikel sebelumnya, untuk mengembalikan grub dijelaskan menggunakan boot-repair. Pada artikel ini akan dijelaskan cara lainnya, yaitu menggunakan perintah pada terminal. Berikut adalah tahapannya:

  1. Masuk ke ubuntu menggunakan live cd, kemudian buka terminal.
  2. Mount partisi tempat ubuntu diinstall.
    sudo mount /dev/sdXY /mnt
  3. Bind direktori yang diperlukan grub untuk mendeteksi sistem operasi lainnya.
    sudo mount --bind /dev /mnt/dev &&
    sudo mount --bind /dev/pts /mnt/dev/pts &&
    sudo mount --bind /proc /mnt/proc &&
    sudo mount --bind /sys /mnt/sys
  4. Masuk kemode “chroot”.
    sudo chroot /mnt
  5. Install , check, kemudian update grub.
    Ganti “X” menjadi huruf sesuai dengan nama harddisk, misal “a” sehingga menjadi “/dev/sda”

    grub-install /dev/sdX
    grub-install --recheck /dev/sdX
    update-grub
  6. Grub telah kembali, keluar dari “chroot”, kemudian unmount.
    exit &&
    sudo umount /mnt/sys &&
    sudo umount /mnt/proc &&
    sudo umount /mnt/dev/pts &&
    sudo umount /mnt/dev &&
    sudo umount /mnt
  7. Reboot.

android open failed: EACCES (Permission denied)

Jika mendapatkan pesan error berikut:

android open failed: EACCES (Permission denied)

bisa jadi karena tidak mempunyai akses untuk menulis ke media external.

Salah satu solusinya adalah mengubah file permissions secara manual. Berikut adalah langkah-langkah untuk mengubah file permission:

  1. Pastikan bahwa perangkat android yang digunakan dalam keadaan rooted.
  2. Buka file manager yang mempunyai hak akses root (misal: ES File Explorer), arahkan kedirektori “/system/etc/permissions”.
  3. Edit “platform.xml” dan cari bagian “<permission name=”android.permission.WRITE_EXTERNAL_STORAGE” >”. Tambahkan grup permission “<group gid=”media_rw” />” sehingga menjadi:
    <permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
        <group gid="sdcard_rw" />
        <group gid="media_rw" />
    </permission>
  4. Simpan, kemudian restart perangkat android.
