ScrollView 不能显示 ImageView 问题？

使用 Button 来替代

Android bug：java.lang.IllegalStateException: Module entity with name: xxx should be available

找到 settings.gradle 文件

在文件里面找到

rootProject.name = xxx

确保这个写的文件名和项目文件名完全一致。尤其是大小写！

mac AndroidStudio 不能查看源码

如果 AndroidStudio 不能查看源码，并且 Download 之后还是一样。那么可以按照下面方式处理。

执行命令

cd ~/Library/Preferences/AndroidStudio3.4/options

进入配置目录。

其中我这里 AndroidStudio 版本为 3.4，如果你的版本为其他，上面的目录应该为 AndroidStudio 加上对应版本号。

然后编辑 jdk.table.xml。

里面有各个 SDK 版本的配置。

假设你 AndroidStudio 提示的是 27 有问题，你查找 27。

可以看到

<name value="Android API 27 Platform" />

往下可以看到下面

<sourcePath>
  <root type="composite">
  </root>
</sourcePath>

发现缺少源码路径配置，添加修改如下：

<sourcePath>
  <root type="composite">
    <root url="file://$USER_HOME$/Library/Android/sdk/sources/android-27" type="simple" />
  </root>
</sourcePath>

保存之后重启 AndroidStudio 应该就可以了。

zsh git log 乱码

该方案是解决使用普通命令，比如 ls 显示中文文件夹没问题，但是 git log 查看 commit 信息中文乱码问题。

在 ~/.zshrc 追加下面两行

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

然后执行 source ~/.zshrc 让配置生效即可

华为手机 log 查看方法

进入拨号界面输入：

*#*#2846579#*#*

点击后台设置->LOG 设置，全打勾

No matching variant of com.android.tools.build:gradle:7.4.2 was found. The consumer was configured to find a runtime of a library compatible with Java 8, packaged as a jar, and its dependencies declared externally, as well as attribute 'org.gradle.plugin.api-version' with value '7.4' but:

AS and module both need set

AS:(Preferences)

module:(right click->Open Module Settings)

After, you can't found dependencies like above for module

Unsupported major.minor version 52.0

修改gradle命令的执行环境。一般命令行打包会出现这个问题。

修改gradle.properties，

添加org.gradle.java.home=/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home

如何解决Unsupported major.minor version 52.0问题？

AndroidStudio logcat 正则无法过滤

需要注意正则要使用空格来隔开，这边发现没有空格会有问题
& 只需要空格
| 需要前后空格加 |
所以如果你想过滤自己的应用程序，使用

package:mine

如果还要在此基础上筛选出 A，则是

package:mine A

如果希望还要筛选出 B，则是

package:mine A | B

注意空格的使用，没有空格，比如下面，可能就什么都筛选不出来

package:mineA|B

Prevent the keyboard from displaying on activity start

just add the follow code in onCreate()

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

AndroidStudio unable support JCEF

Select Help > Find Action from the Android Studio menu.
Enter "Choose Boot Java Runtime for the IDE" and select it from the suggestion list.
Select the runtime that comes with JCEF support as shown in the image below:

External Native Build Issues: SIMPLE: Error configuring

Mac 解决方法（其他系统类似）：

到官网下载 ninja文件

然后将这个文件拷贝到/usr/local/bin目录下

重新编译项目即可

参考链接：
External Native Build Issues: SIMPLE: Error configuring

javax.net.ssl.SSLHandshakeException: SSL handshake aborted: ssl=0x7e3c04d1c0: I/O error during system call, Connection reset by peer

除了可能是代码逻辑之外，还有可能是公司 Wi-Fi 问题，即网络问题

Unable to negotiate with xx.xx.xx.xx port xxxx: no matching host key type found. Their offer: ssh-rsa fatal: Could not read from remote repository.

在 ~/.ssh/config 文件里面，增加

Host *
    PubkeyAcceptedAlgorithms +ssh-rsa
    HostkeyAlgorithms +ssh-rsa

看下依赖里面是否有下面依赖：

Android 10 adb ifconfig: ioctl 8927: Permission denied

Android 10 使用 adb 进行无线调试时，发现想查询设备 ip 地址出现错误：

ifconfig: ioctl 8927: Permission denied

可以改用如下命令：

ip -f inet addr show

check you module build.gradle, make the minifyEnabled's value to be false.
minifyEnabled false

Q2:

Caused by: java.lang.RuntimeException: java.lang.IllegalStateException: aidl is missing

it means you compileSdkVersion and buildToolsVersion is not very fit.
I am use 25 and 25.0.0 and get this error.Then I instead of 23 and 23.0.2.And this error is solve.

Q3:

Caused by: org.gradle.api.InvalidUserDataException: File 'project/module/build/intermediates/res/
