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.

GIT: unpack failed: error Missing tree

git push 할 경우 아래와 같은 나오면서 안되는 경우가 있었습니다.

error: unpack failed: error Missing tree 8fe84b8d352eedc3acd46a17de0531d38d5de4c2
fatal: Unpack error, check server log
To ssh://codewalker@xxxxxx.or.kr:29418/android_external_wpa_supplicant_8
 ! [remote rejected] HEAD -> refs/for/4412_4.4.4_master (n/a (unpacker error))

딱히 googling하여도 답을 못 찾겠더군요.

https://www.google.co.kr/webhp?sourceid=chrome-instant&ion=1&espv=2&es_th=1&ie=UTF-8#q=%22Error:+unpack+failed:+error+Missing+tree%22&newwindow=1&start=10

수정한 파일이 특이하게 아래 포맷으로 되어 있었습니다.
$ file android.config
android.config: ISO-8859 text

일반적으로 ASCII text인데 말이죠.
wifi_display.c:               C source, ASCII text
wifi_display.h:               ASCII text

그래서 파일을 지우고 다시 만들어 ASCII text로 만들고 수정하고 push 하니 문제가 없더군요.

$ file android.config
android.config: ASCII text

결론: unpack failed가 나면 file의 속성을 확인하고 ASCII text로 만들어 보자.

apk unpack and repack

기존에 누군가가 만들어준 GAppsInstaller_kk.apk가 문제가 있다는 글이 포럼에 올라 왔다.

http://forum.odroid.com/viewtopic.php?f=113&t=11854&start=50

여기서 링크에 있는 GAPPs를 사용하면 문제가 해결 된다는 글이 있다.

http://wiki.cyanogenmod.org/w/Google_Apps

그래서 GAppsInstaller_kk.apk 를 풀어 위에 아래 파일로 대체 하려고 한다.

https://goo.im/gapps/gapps-kk-20140105-signed.zip/

gapps-kk-20140105-signed.zip 압축을 푼다.

 system 폴더에서 모든 파일을 선택한다.

우측 클릭 메뉴에서 Compress...를 선택한다.

gapps.tar.xz로 압축한다.

gapps.tar.xz를 gapps.xz로 변경한다.

이제 apk를 풀고 묶는 툴을 설치한다.

http://ibotpeaches.github.io/Apktool/

Apktool 2.x 버전과 Java 1.7 을 사용하였다.

http://ibotpeaches.github.io/Apktool/install/

저는 안드로이드 빌드를 위하여 1.6과 1.7 두가지 모두 설치 되어 있어서 아래와 같이 openjdk로 변경합니다.

$ sudo update-alternatives --config java

There are 3 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                            Priority   Status
------------------------------------------------------------
  0            /usr/lib/jvm/java-6-oracle/jre/bin/java          1073      auto mode
  1            /usr/lib/jvm/java-6-oracle/jre/bin/java          1073      manual mode
  2            /usr/lib/jvm/java-6-sun/jre/bin/java             63        manual mode
* 3            /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java   1071      manual mode

Press enter to keep the current choice[*], or type selection number:
