1. Could not find com.android.tools.build:aapt2:3.3.2-5309881

build失败，报错

解决办法：在项目下的build.gradle repositories下加入 google()

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        google()
    }
}

2. This version of Android Studio cannot open this project, please retry with Android Studio 3.4 or newer.

解决办法：升级AndroidStudio或者gradle版本降级

3. Circular dependency between the following tasks:

FAILURE: Build failed with an exception.

* What went wrong:
Circular dependency between the following tasks:
:llib:compileDebugAidl
\--- :llib:compileDebugAidl (*)

(*) - details omitted (listed previously)
...

解决办法：更换项目下repositories的顺序，如

repositories {
    mavenCentral()
    maven {
        url 'https://jitpack.io'
    }
    maven { url "https://dl.bintray.com/thelasterstar/maven/" }

    google()
    jcenter()
}

4. com.android.ide.common.signing.KeytoolException: Failed to read key ???

.properties用来存放app名称或者keystore信息时，出现中文会读取乱码。

解决办法：首先项目的文件编码都改为utf-8

然后取值的时候，如取keystore alias使用new String(KEYSTORE_ALIAS.getBytes("iso8859-1"), "UTF-8")
