可能原因
adb server 进程想使用的 5037 端口被占用。
解决方案
找到占用 5037 端口的进程，然后终止它。以 Windows 下为例：
netstat -ano | findstr LISTENING
... TCP 0.0.0.0:5037 0.0.0.0:0 LISTENING 1548 ...
这里 1548 即为进程 ID，用命令结束该进程：
taskkill /PID 1548
然后再启动 adb 就没问题了。
com.android.ddmlib.AdbCommandRejectedException
在 Android Studio 里新建一个模拟器，但是用 adb 一直连接不上，提示：
com.android.ddmlib.AdbCommandRejectedException: device unauthorized. This adb server's $ADB_VENDOR_KEYS is not set Try 'adb kill-server' if that seems wrong. Otherwise check for a confirmation dialog on your device.
在手机上安装一个终端然后执行 su 提示没有该命令，这不正常。
于是删除该模拟器后重新下载安装一次，这次就正常了。

aapt相关命令
Android Asset Packaging Tool
Usage: aapt l[ist] [-v] [-a] file.{zip,jar,apk} List contents of Zip-compatible archive.
aapt d[ump] [--values] [--include-meta-data] WHAT file.{apk} [asset [asset ...]] strings Print the contents of the resource table string pool in the APK. badging Print the label and icon for the app declared in APK. permissions Print the permissions from the APK. resources Print the resource table from the APK. configurations Print the configurations in the APK. xmltree Print the compiled xmls in the given assets. xmlstrings Print the strings of the given compiled xml assets.
Package the android resources. It will read assets and resources that are supplied with the -M -A -S or raw-files-dir arguments. The -J -P -F and -R options control which files are output.
aapt c[runch] [-v] -S resource-sources ... -C output-folder ... Do PNG preprocessing on one or several resource folders and store the results in the output folder.
aapt s[ingleCrunch] [-v] -i input-file -o outputfile Do PNG preprocessing on a single file.
aapt v[ersion] Print program version.
Modifiers: -a print Android-specific data (resources, manifest) when listing -c specify which configurations to include. The default is all configurations. The value of the parameter should be a comma separated list of configuration values. Locales should be specified as either a language or language-region pair. Some examples: en port,en port,land,en_US -d one or more device assets to include, separated by commas -f force overwrite of existing files -g specify a pixel tolerance to force images to grayscale, default 0 -j specify a jar or zip file containing classes to include -k junk path of file(s) added -m make package directories under location specified by -J -u update existing packages (add new, replace older, remove deleted files) -v verbose output -x create extending (non-application) resource IDs -z require localization of resource attributes marked with localization="suggested" -A additional directory inwhich to find raw asset files -G A file to output proguard options into. -D A file to output proguard options for the main dex into. -F specify the apk file to output -I add an existing package to base include set -J specify where to output R.java resource constant definitions -M specify full path to AndroidManifest.xml to include in zip -P specify where to output public resource definitions -S directory inwhich to find resources. Multiple directories will be scanned and the first match found (left to right) will take precedence. -0 specifies an additional extension forwhich such files will not be stored compressed in the .apk. An empty string means to not compress any files at all. --debug-mode inserts android:debuggable="true"in to the application node of the manifest, making the application debuggable even on production devices. --include-meta-data when used with "dump badging" also includes meta-data tags. --pseudo-localize generate resources for pseudo-locales (en-XA and ar-XB). --min-sdk-version inserts android:minSdkVersion in to manifest. If the version is 7 or higher, the default encoding for resources will be in UTF-8. --target-sdk-version inserts android:targetSdkVersion in to manifest. --max-res-version ignores versioned resource directories above the given value. --values when used with "dump resources" also includes resource values. --version-code inserts android:versionCode in to manifest. --version-name inserts android:versionName in to manifest. --replace-version If --version-code and/or --version-name are specified, these values will replace any value already in the manifest. By default, nothing is changed if the manifest already defines these attributes. --custom-package generates R.java into a different package. --extra-packages generate R.java for libraries. Separate libraries with ':'. --generate-dependencies generate dependency files in the same directories for R.java and resource package --auto-add-overlay Automatically add resources that are only in overlays. --preferred-density Specifies a preference for a particular density. Resources that do not match this density and have variants that are a closer match are removed. --split Builds a separate split APK for the configurations listed. This can be loaded alongside the base APK at runtime. --feature-of Builds a split APK that is a feature of the apk specified here. Resources in the base APK can be referenced from the the feature APK. --feature-after An app can have multiple Feature Split APKs which must be totally ordered. If --feature-of is specified, this flag specifies which Feature Split APK comes before this one. The first Feature Split APK should not define anything here. --rename-manifest-package Rewrite the manifest so that its package name is the package name given here. Relative class names (for example .Foo) will be changed to absolute names with the old package so that the code does not need to change. --rename-instrumentation-target-package Rewrite the manifest so that all of its instrumentation components target the given package. Useful when used in conjunction with --rename-manifest-package to fix tests against a package that has been renamed. --product Specifies which variant to choose for strings that have product variants --utf16 changes default encoding for resources to UTF-16. Only useful when API level is set to 7 or higher where the default encoding is UTF-8. --non-constant-id Make the resources ID non constant. This is required to make an R java class that does not contain the final value but is used to make reusable compiled libraries that need to access resources. --shared-lib Make a shared library resource package that can be loaded by an application at runtime to access the libraries resources. Implies --non-constant-id. --app-as-shared-lib Make an app resource package that also can be loaded as shared library at runtime. Implies --non-constant-id. --error-on-failed-insert Forces aapt to return an error if it fails to insert values into the manifest with --debug-mode, --min-sdk-version, --target-sdk-version --version-code and --version-name. Insertion typically fails if the manifest already defines the attribute. --error-on-missing-config-entry Forces aapt to return an error if it fails to find an entry for a configuration. --output-text-symbols Generates a text file containing the resource symbols of the R class in the specified folder. --ignore-assets Assets to be ignored. Default pattern is: !.svn:!.git:!.ds_store:!*.scc:.*:<dir>_*:!CVS:!thumbs.db:!picasa.ini:!*~ --skip-symbols-without-default-localization Prevents symbols from being generated for strings that do not have a default localization --no-version-vectors Do not automatically generate versioned copies of vector XML resources. --no-version-transitions Do not automatically generate versioned copies of transition XML resources. --private-symbols Java package name to use when generating R.java for private resources.
