android_usb_devices

有时候android设备链接到电脑的时候会显示error:insufficient permissions for device,解决方法就是在/etc/udev/rules.d/51-android.rules 加入设备的idVender和idProduct,于是就有了下面这个自动添加的脚本.

#!/bin/bash
RULES=/etc/udev/rules.d/51-android.rules
TMP_USB_1=tmp_usb_1
TMP_USB_2=tmp_usb_2
TMP_USB=diff_usb

echo -n "请把手机链接电脑后,按回车:"

read user_input
lsusb > $TMP_USB_1
cat -n $TMP_USB_1

echo -n "请把手机拔掉后,按回车:"
read user_input

lsusb > $TMP_USB_2
cat -n $TMP_USB_2

diff $TMP_USB_1 $TMP_USB_2 > $TMP_USB

diff_usb_str=`sed -n '2p' $TMP_USB`
#echo ${diff_usb_str}

sub_str=${diff_usb_str:25:9}
#echo $sub_str

idVendor=${sub_str:0:4}
idProduct=${sub_str:5:4}

insert='SUBSYSTEM==\"usb\", ATTRS{idVendor}==\"'${idVendor}'\", ATTRS{idProduct}==\"'${idProduct}'\",MODE=\"0666\"'

sudo touch $RULES
sudo sh -c "echo $insert >> $RULES"
sudo chmod a+x $RULES

echo -n "请再次把手机链接电脑,之后按回车:"
read user_input

adb kill-server && adb devices

echo "看到设备表示已经成功了,如果还是没有显示正常,重启一下电脑就好了"

rm $TMP_USB $TMP_USB_1 $TMP_USB_2

使用方法

把上面脚本内容保存到usb.sh中,执行bash usb.sh就行.

switch-jdk-version

很多时候,我们在开发的时候,需要不同的jdk,手动切换比较麻烦,因此我写了个脚本,方便快速切换JDK版本.

#!/bin/bash

JAVA_7_HOME=/usr/lib/jvm/java-7-openjdk-amd64/
JAVA_8_HOME=/usr/lib/jvm/java-8-openjdk-amd64/

echo -e "\n输入编号以选择JDK版本:\n\t1. JDK6($JAVA_6_HOME) \n\t2. JDK7($JAVA_7_HOME) \n\t3. JDK8($JAVA_8_HOME)\n"
echo -n "直接回车会直接选择JDK7:"

把上面的脚本放到源码根目录执行一下就好了

Apk签名总汇

开发中,Apk签名是一件不大也不小的事,如果你做过微博相关的开发,你可能遇到如下情景:

用Eclipse或者AS直接点run生成的apk跑在手机上根本不能授权成功,每次需要导出release版本,很烦.

如果你基于系统源码开发或者二次开发系统预置App,你的流程可能是:

mm 或者 mmm 编译出apk,之后再push 到/system/app/ 下,或者用adb install -r 安装到手机.
否根本无法安装,因为签名不一样.

因此我搜集整理了如下内容,解决了以上两个难题,任何app都可以直接再IDE中直接run,并debug.

日常开发

修改Eclips或者Android Studio的默认签名文件

通常情况下,我们debug版本的apk和正式release的apk签名是不一样.特别开发一些有签名限制
的App的时候,就造成了调试上的不方便.

如何修改?

Eclipse

Eclips -> Window -> Preference -> Androi -> Buil.
在 Custom debug keystore 指定自己的 debug.keystore 就可以了.(注意签名文件的名字
不必是debug.keystore).

Androi的 Studio

android {
    signingConfigs {
        debug {
            storeFile file("debug.keystore")
        }
    }
}

疑问?

如何创建自己的debug.keystore?

keytool -genkey -v -keystore debug.keystore -alias androiddebugkey -storepass android -keypass android -keyalg RSA -validity 14000
// 这样你就创建了一个 debug.keystore

如何把现有签名文件,转换成Eclipse或Android Studio可用的`debug.keystore`?

假如你现在的签名文件是:my.keystore.

修改my.keystore 的密码为:android

keytool -storepasswd -keystore my.keystore

修改my.keystore 的alias为:androiddebugkey

keytool -changealias -keystore my.keystore -alias my_name -destalias androiddebugkey

修改alias 的密码为:android

keytool -keypasswd -keystore my.keystore -alias androiddebugkey

执行完上面三步,你的debug.keystore 就创建完成了,替换上去就行.

系统源码开发

源码签名文件在哪?

SOURCE_CODE/build/target/product/security/

$:ls
media.pk8       platform.pk8       README    shared.pk8       signapk.jar  testkey.x509.pem
media.x509.pem  platform.x509.pem  Root.zip  shared.x509.pem  testkey.pk8  update.zip

但如果你在一家手机厂商工作,厂商一般不会直接用而是会进行定制:

SOURCE_CODE/vendor/CUSTOM_VENTER_NAME/security/

$: ls
media.pk8       platform.pk8       releasekey.pk8       shared.pk8       testkey.pk8
media.x509.pem  platform.x509.pem  releasekey.x509.pem  shared.x509.pem  testkey.x509.pem

如何用系统签名文件签名apk?

java -jar platform.x509.pem platform.pk8 UnSign.apk Signed.apk

zipalign优化apk

zipalign -v 4 MyDemo_signed.apk MyDemo_new.apk

是否用zipalign优化过

zipalign -c -v 4 MyDemo.apk

如何把`platform.x509.pem platform.pk8` 转成`debug.keystore`?

生成shared.priv.pem

openssl pkcs8 -in platform.pk8 -inform DER -outform PEM -out shared.priv.pem -nocrypt

生成pkcs12

openssl pkcs12 -export -in platform.x509.pem -inkey shared.priv.pem -out shared.pk12 -name androiddebugkey
// 如果生成的`debug.keystore`要用在Eclipse中使用,请输入密码:`android`,否则请输入自己的签名即可.

生成debug.keystore

keytool -importkeystore -deststorepass android -destkeypass android -destkeystore debug.keystore -srckeystore shared.pk12 -srcstoretype PKCS12 -srcstorepass android -alias androiddebugkey
