<h2>Linux and OS X</h2>

Use ps/grep/cut to grab the PID, then grep for logcat entries with that PID. Here's the command I use:

<pre><code>adb logcat | grep -F "`adb shell ps | grep com.asanayoga.asanarebel | tr -s [:space:] ' ' | cut -d' ' -f2`"
</code></pre>

(You could improve the regex further to avoid the theoretical problem of unrelated log lines containing the same number, but it's never been an issue for me)

This also works when matching multiple processes.

<h2>Windows</h2>

On Windows you can do:

<pre><code>adb logcat | findstr com.example.package

ADT v15 for Eclipse let you specify an application name (which is actually the package value in your androidmanifest.xml).

I love being able to filter by app, but the new logcat has a bug with the autoscroll. When you scroll up a little to look at previous logs, it automatically scrolls back to the bottom in a couple seconds. It seems scrolling 1/2 way up the log does keep it from jumping back to the bottom, but that's often useless.

EDIT: I tried specifying an app filter from the command-line -- but no luck. If someone figures this out OR how to stop the autoscroll, please let me know.

This is probably the simplest solution. 

On top of a solution from Tom Mulcahy, you can further simplify it like below:

<pre><code>alias logcat="adb logcat | grep `adb shell ps | egrep '\bcom.your.package.name\b' | cut -c10-15`"
</code></pre>

Usage is easy as normal alias. Just type the command in your shell:

<pre><code>logcat
</code></pre>

The alias setup makes it handy. And the regex makes it robust for multi-process apps, assuming you care about the main process only. 

Of coz you can set more aliases for each process as you please. Or use hegazy's solution. :)

In addition, if you want to set logging levels, it is

<pre><code>alias logcat-w="adb logcat *:W | grep `adb shell ps | egrep '\bcom.your.package.name\b' | cut -c10-15`"
</code></pre>

In order to access the logcats you first need to install ADB command-line tool. ADB command-line tool is a part of android studio platform tools and can be downloaded from <a href="https://developer.android.com/studio/releases/platform-tools" rel="nofollow noreferrer">here</a>. After this, you need to set the path/environment <a href="https://developer.android.com/studio/command-line/variables" rel="nofollow noreferrer">variable</a> for adb tools. Now you can access logcat from eclipse terminal/ intellij terminal or mac terminal in case you are using a macbook.
<code>adb logcat</code> : To get entire logcat.
<code>adb shell pidof 'com.example.debug'</code> : To get the process id of your app.
<code>adb logcat pid=&lt;pid&gt;</code> : To get logcat specific to your app.
<code>adb logcat pid=&lt;pid&gt;|grep 'sometext'</code> : To filter logcat on basis of some text.
For more info about filtering logcats read <a href="https://developer.android.com/studio/command-line/logcat" rel="nofollow noreferrer">this</a>.

I have different approach, you can try access to local device's shell.
<code>adb shell</code>
and then follow by
<code>logcat | grep com.package.name</code>
This print all containing that package.
Alternatively, You can try <code>flutter logs --verbose</code>

I tried to use Tom Mulcahy's answer but unfortunately it was not working for applications with multiple processes so I edit it to fit my needs.

adb logcat | grep -E "$GREP_TEXT"

Also if you have rolled out your app and you want to fetch error logs from released app, you can use below command.
adb logcat AndroidRuntime:E *:S

blocks|key|827231|text|我通常会在日志消息中添加一些内容，以使其与众不同。或者例如unity应用程序，您可以使用"Unity“作为匹配字符串。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|827232|对于mac：|827233|adb+logcat+%7C+grep+"MyUniqueString"+|code-block|syntax|javascript|827234|对于Windows+(powershell+)：|827235|adb+logcat+%7C+Select-String+"MyUniqueString"|827236|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|P|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|Q|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|R|8|@]|9|@]|A|$]]|$1|K|3|L|5|F|7|S|8|@]|9|@]|A|$G|H]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

I am usually adding something in the log messages to make it distinct. Or for example unity app you can use &quot;Unity&quot; as matching string.
For mac :
<pre><code>adb logcat | grep &quot;MyUniqueString&quot; 
</code></pre>
for Windows (powershell ):
<pre><code>adb logcat | Select-String &quot;MyUniqueString&quot;
</code></pre>

echo "PID's: $APPIDS"

I observed that when i use Logcat with Eclipse with ADT for Android, I get messages from many other applications as well. Is there a way to filter this and show only messages from my own application only.

Filter LogCat to get only the messages from My Application in Android?

命令行工具

Android Studio

Android

Windows

Eclipse

Linux

Ionic

我观察到，当我在Eclipse和ADT for Android中使用Logcat时，我也会收到来自许多其他应用程序的消息。有没有办法过滤它，只显示来自我自己的应用程序的消息。
