Questions

Q1: This version of Android Studio is incompatible with the Gradle Plugin used. Try disabling Instant Run(or updating either the IDE or the Gradle plugin to the latest version)

Android Studio > Preferences > Build,Execution,Deployment > Instant Run > 取消勾选所有

Q2: com.android.server.job.controllers.JobStatus.getUid()-->NullPointerException

https://issuetracker.google.com/issues/37018640 Android 系统 Bug。

解决方法：

Change:
    public boolean onStartJob(JobParameters params) {
        Log.i(TAG, "ON START JOB: " + params.getJobId());
        jobFinished(params, false);
        return false;
    }

to :
public boolean onStartJob(JobParameters params) {
        Log.i(TAG, "ON START JOB: " + params.getJobId());
        return false;
    }

or:
public boolean onStartJob(JobParameters params) {
        Log.i(TAG, "ON START JOB: " + params.getJobId());
        jobFinished(params, false);
        return true;
    }

Q3: Fatal Exception: java.lang.IllegalArgumentException: pointerIndex out of range

Q4: A problem occurred starting process 'command 'node'

因为没找到 /usr/local/bin/node，所以手动创建

$ command -v node
/Users/bell/.nvm/versions/node/v8.9.1/bin/node
$ ln -s /Users/bell/.nvm/versions/node/v8.9.1/bin/node /usr/local/bin/node

Q5: gradle sync failed caused: java.lang.NullPointerException

File -> Invalidate Caches / Restart -> Invalidate and Restart Build -> Clean Project

Q6: ParseError at [row,col]:[1,1] Message: 前言中不允许有内容。

./gradlew app:shrinkReleaseRes 可能报如下错：

* What went wrong:
Execution failed for task ':app:shrinkShimoReleaseRes'.
> Multiple task action failures occurred:
   > A failure occurred while executing com.android.build.gradle.internal.transforms.ShrinkProtoResourcesAction
      > ParseError at [row,col]:[1,1]
        Message: 前言中不允许有内容。

参考 SAX Error – Content is not allowed in prolog 出现这个问题的原因有两个

1. XML 文件最前面带有非 < 字符

2. XML 编码方式为 UTF-8 With BOM

参考 Elegant way to search for UTF-8 files with BOM? 在 Mac 上执行

find . -name "*.xml" |while read file;do [ "`head -c3 -- "$file"`" == $'\xef\xbb\xbf' ] && echo "found BOM in: $file";done

找出所有 UTF-8 with BOM 编码的 XML 文件，然后用 vscode 转成 UTF-8 编码

  1. 点击对应文件点击右下角的 UTF-8 with BOM
  2. 选择 Save with Encoding
  3. 选择 UTF-8
