Google Play Store on ODROID-C2.

http://codewalkerster.blogspot.kr/2016/06/how-to-install-google-play-store-on.html

Visit http://dn.odroid.com/GAPPS and download GAppsInstaller_lollipop.apk

Install

Rebooted and log in google.

 Check Play store version.

If you Installed youtube app, You must update Google Play services too.

If you update Google Play service, You will go though this situation.
I do not have solution for that. You must reinstall android image.

Check Play store version like this. Play store will update automatically.

Fist Update Google Store and must update Google Play Services later.

Ctrl + Alt + Del doesn't reboot Android

echo 0 > /proc/sys/kernel/ctrl-alt-del

Or edit init.xxx.rc

 write /proc/sys/kernel/ctrl-alt-del 0

overscan for ODROID-C1 Ubuntu

1. search overscan values.

Read default values
root@odroid:~# cat /sys/class/graphics/fb0/window_axis
window axis is [100 100 1919 1079]
root@odroid:~#

Try to set overscan values
root@odroid:~# echo 100 100 1919 1079 > /sys/class/graphics/fb0/window_axis
root@odroid:~# echo 0x10001 > /sys/class/graphics/fb0/free_scale

2. make script(overscan.sh)

root@odroid:~# cat overscan.sh
#!/bin/bash

echo 100 100 1919 1079 > /sys/class/graphics/fb0/window_axis
echo 0x10001 > /sys/class/graphics/fb0/free_scale 
root@odroid:~#

3. Auto-start overscan shell script on Ubuntu.

root@odroid:~# cp overscan.sh /etc/init.d/
root@odroid:~# sudo update-rc.d overscan.sh defaults

안드로이드 repo 특정 날짜로 돌려서 빌드하기

급하게 아래 안드로이드 project를 build 해야 할 일이 생겼다.

https://github.com/voodik/android/tree/cm-12.1_5422

오래전에 받아 놓은 소스를 repo sync 후 빌드 하니 역시나 컴파일 에러가 난다.

git log를 보면 계속 작업을 진행하였지만 release한 버전에 tag가 없다. 그래서 원하는 버전으로 돌리기가 어렵다.

아래 포럼에 보면 마지막 7월 7일이 마지막 버전이다.
http://forum.odroid.com/viewtopic.php?f=94&t=9316

googling 하여 보니 git rev-list를 통해 특정 날짜로 돌릴 수 있다. 그래서 아래와 같이 모든 프로젝트를 7월 7일로 돌렸다.

우선 manifest를 7월 7일로 돌린다.

$ cd .repo/manifsets/

$ git rev-list -n 1 --before="2015-07-07 24:00:00" default | xargs -i git reset --hard {}

돌린 default.xml을 복사하여 둔다/

$ cp default.xml ../default_0707.xml

다시 마지막으로 원복시킨다.

$ git reset --hard origin/cm-12.1_5422

그리고 7월 7일 내용을 하나의 commit으로 올린다.

$ mv ../default_0707.xml default.xml

$ git add default.xml

$ git commit

$ repo sync

위와 같이 하지 않으면 repo sync시 다시 최신 소스로 돌아가 버린다.

마지막으로 모든 프로젝트도 동일하게 7월 7일로 reset 한다.

$ repo forall -c 'git rev-list -n 1 --before="2015-07-07 24:00:00" cm-12.1_5422 | xargs -i git reset --hard {}'

빌드를 진행한다.

Android File Chooser and URI to File Path.

파일을 Intent.ACTION_GET_CONTENT을 이용하여 선택하고 URI를 File Path로 변환하기

Image 나 Video 같은 파일을 얻어오는 예제는 많지만 일반 파일을 선택하는 예제가 없어서 며칠 찾아 보다가 직접 external.db에서 값을 얻어와야 한다는 결론을 얻었습니다.

/data/data/com.android.providers.media/databases 경로에 가면 모든 파일을 DB로 관리합니다.

root@odroidc:/data/data/com.android.providers.media/databases # ls -l
-rw-rw---- u0_a4    u0_a4      163840 2015-08-25 03:23 external.db
-rw-rw---- u0_a4    u0_a4       32768 2015-08-25 03:21 external.db-shm
-rw-rw---- u0_a4    u0_a4       28872 2015-08-25 03:21 external.db-wal
-rw-rw---- u0_a4    u0_a4      212992 2015-08-20 06:22 internal.db
-rw------- u0_a4    u0_a4       32768 2015-08-25 03:21 internal.db-shm
-rw------- u0_a4    u0_a4      453232 2015-08-25 03:21 internal.db-wal
root@odroidc:/data/data/com.android.providers.media/databases #

external.db를 sqliteman 프로그램을 이용하여 열어 보시면 아래와 같이 되어 있습니다.
files 테이블에 '_data'란 column에 실제 file path가 들어 있습니다.

private static final int FILE_SELECT_CODE = 0;

private void showFileChooser() {
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_GET_CONTENT);

아래와 같이 할 경우 mime-type에 해당하는 파일만 선택 가능해 집니다.
    intent.setType("application/zip");
    intent.addCategory(Intent.CATEGORY_OPENABLE);

    try {
        startActivityForResult(
                Intent.createChooser(intent, "Select a File"),
                FILE_SELECT_CODE);
    } catch (android.content.ActivityNotFoundException ex) {
        // Potentially direct the user to the Market with a Dialog
        Toast.makeText(this, "Please install a File Manager.",
                Toast.LENGTH_SHORT).show();
    }
}

showFileChooser()를 실행하면 아래와 같은 file dialog가 실행 됩니다.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    switch (requestCode) {
        case FILE_SELECT_CODE:
            if (resultCode == RESULT_OK) {
                // Get the Uri of the selected file
                Uri uri = data.getData();
URI -> real file path
                String file_path = getRealPathFromURI(uri);
            }
            break;
    }
    super.onActivityResult(requestCode, resultCode, data);
}


private String getRealPathFromURI(Uri uri) {
    String filePath = "";
    filePath = uri.getPath();
경로에 /storage가 들어가면 real file path로 판단
    if (filePath.startsWith("/storage"))
        return filePath;

    String wholeID = DocumentsContract.getDocumentId(uri);

wholeID는 파일명이 abc.zip이라면 /document/B5D7-1CE9:abc.zip와 같습니다.

    // Split at colon, use second item in the array
    String id = wholeID.split(":")[1];

    Log.e(TAG, "id = " + id);

    String[] column = { MediaStore.Files.FileColumns.DATA };

파일의 이름을 통해 where 조건식을 만듭니다.

    String sel = MediaStore.Files.FileColumns.DATA + " LIKE '%" + id + "%'";

External storage에 있는 파일의 DB를 접근하는 방법 입니다.
    Cursor cursor = getContentResolver().query(MediaStore.Files.getContentUri("external"),
            column, sel, null, null);

SQL문으로 표현하면 아래와 같이 되겠죠????
SELECT _dtat FROM files WHERE _data LIKE '%selected file name%'

    int columnIndex = cursor.getColumnIndex(column[0]);

    if (cursor.moveToFirst()) {
        filePath = cursor.getString(columnIndex);
    }
    cursor.close();
    return filePath;
}

How to write images without fastboot on ODROID-XU4(android)

You can not use fastboot on ODROID-XU4, because It doesn't have USB otg port.

How to write images?

First! setup adb connection or copy image to fat partition.

http://codewalkerster.blogspot.kr/2015/07/adb-connect-over-tcpip-when-multiple.html

Push image to fat partition.

$ adb push xxxx.img /storage/sdcard0/
$ adb reboot

Enter u-boot prompt.
