Try to make sure that the soft keyboard is not showing. It can easily be closed with the closeSoftKeyboard ViewAction. 

Moreover, make sure that system animations are disabled. Under Settings -> Developing Options turn off the following: 

<ul>
<li>Window animation scale</li>
<li>Transition animation scale</li>
<li>Animator duration scale</li>
</ul>

Also, this might be caused by ANR dialogs from other apps. 

There's been an issue reported <a href="https://code.google.com/p/android-test-kit/issues/detail?id=44">here</a> as well.

blocks|key|135137|text|诀窍是读取错误的完整堆栈跟踪。在中间，有一些关键的信息，比如：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|135138|Caused+by:+java.lang.RuntimeException:+Action+will+not+be+performed+because+the+target+view+does+not+match+one+or+more+of+the+following+constraints:

The trick is to read the full stack-trace of the error. In the middle, there is some crucial piece of information like this:

<pre class="lang-none prettyprint-override"><code>Caused by: java.lang.RuntimeException: Action will not be performed because the target view does not match one or more of the following constraints:
at least 90 percent of the view's area is displayed to the user.
Target view: "ImageView{id=2131492903, res-name=button_hamburger, desc=opens the side drawer, visibility=VISIBLE, width=64, height=64, has-focus=false, has-focusable=false, has-window-focus=true, is-clickable=true, is-enabled=true, is-focused=false, is-focusable=false, is-layout-requested=false, is-selected=false, root-is-layout-requested=false, has-input-connection=false, x=6.0, y=6.0}"
</code></pre>

which explains the error in detail.

I had the same problem because the soft keyboard was overlapping the element. I used scrollTo() followed by click() to resolve the issue.

<pre><code>onView(withId(R.id.btn))
 .perform(scrollTo())
 .perform(click());
</code></pre>

If above does not work, try adding the following first:

<pre><code>onView(withId(R.id.myEditText)).perform(closeSoftKeyboard());
</code></pre>

The <code>error</code> was caused by <code>UI</code> thread block. Please check your <code>target Activity code</code>, especially the <code>setUp</code> or <code>init</code> function.

I have met the same <code>error</code>, there is a wrong <code>listener</code> in UI thread which always be called. When I remove the <code>listener</code>, the <code>error</code> could be fixed.

blocks|key|2917580|text|我遇到了同样的问题，并通过改变元素的位置解决了这个问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2917581|在我尝试单击的位置上没有元素。尝试单击位置3，但元素位于第二位置(完全忘记索引从0开始)，因此，我更改了元素的位置，现在它可以正常工作了|2917582|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

I had the same issue, And solved it by changing the position of the element.

There is no element on the position where I was trying to click. Trying to click on position 3 but the element is at 2nd position(Completely forgot that index starts from 0)
So, I changed the position of the element and its working perfectly now

blocks|key|136268|text|我甚至在使用的时候也有这个问题|type|unstyled|depth|inlineStyleRanges|entityRanges|data|136269|onView(withId(R.id.myEditText)).perform(closeSoftKeyboard());|code-block|syntax|javascript|136270|我发现，在我的例子中，在一些设备上，我每次使用时都会使用|136271|onView(withId(R.id.myEditText)).perform(TypeTextAction());|136272|这就像系统在另一个键盘上堆叠了一个新的键盘，所以解决了我的问题是每次都使用closeSoftKeyboard()+I+use+TypeTextAction就像这样。|offset|length|style|BOLD|136273|onView(withId(R.id.myEditText)).perform(typeTextAction(),+closeSoftKeyboard());|136274|因此，如果我需要编辑一个表单，它将如下所示：|136275|onView(withId(R.id.myEditText1)).perform(typeTextAction(),+closeSoftKeyboard());

I had that problem even using

<pre><code>onView(withId(R.id.myEditText)).perform(closeSoftKeyboard());
</code></pre>

What I found out, was that in my case, on some devices, Each Time I used

<pre><code>onView(withId(R.id.myEditText)).perform(TypeTextAction());
</code></pre>

It was like the system stacked a new keyboard on top of another, so what solved my problem was to ALWAYS use closeSoftKeyboard() EVERY-TIME I used TypeTextAction Like this.

<pre><code>onView(withId(R.id.myEditText)).perform(typeTextAction(), closeSoftKeyboard());
</code></pre>

So if I needed to edit a form it would be like: 

<pre><code>onView(withId(R.id.myEditText1)).perform(typeTextAction(), closeSoftKeyboard());
onView(withId(R.id.myEditText2)).perform(typeTextAction(), closeSoftKeyboard());
onView(withId(R.id.myEditText3)).perform(typeTextAction(), closeSoftKeyboard());
onView(withId(R.id.myEditText4)).perform(typeTextAction(), closeSoftKeyboard());
</code></pre>

blocks|key|2704907|text|发生这种情况的原因很少。在我的例子中，这是因为在单击一个按钮后，有一个progress+bar一直在旋转，所以请确保如果有网络呼叫或等待进程，在收到回调后停止进度条。另外，执行单击会等待某些操作的发生，因此请确保您不只是单击，还会在执行单击时执行操作。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2704908|entityMap^0|Z|C|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

there are few reasons this can happen. in my case it was because after clicking a button there was a <code>progress bar</code> that continued spinning forever, so make sure if there is a network call or some waiting process, you stop progress bar after callback is received.
also performing a click waits for some action to happen so make sure you are not just clicking but also performing action when click is performed.

blocks|key|137600|text|TestCase中的一种可能性是，如果您使用LiveData执行数据库操作，那么您应该避免使用下面的规则。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|137601|@Rule+public+InstantTaskExecutorRule+instantTaskExecutorRule+=+InstantTaskExecutorRule()；|137602|删除这些行后，TestCase可以完美地工作。|137603|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

One Possibility in your TestCase is that if you perform database operations using LiveData so you should avoid use below Rule.

@Rule
public InstantTaskExecutorRule instantTaskExecutorRule = new InstantTaskExecutorRule();

After Removing these Line TestCase work Perfectly.

blocks|key|138288|text|对我来说，就像埃里克·阿亚说的那样。但我并不是每次都关闭de键盘，就在我需要“更换键盘”之前和之后，因为我正在输入一个数字Edittext。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|138289|++++//Type+the+user+data

For me it was like Eric Aya said. But I didn't close de keyboard everytime, just before and after I needed to &quot;change the keyboard&quot; because I was typing a number Edittext.
<pre><code> //Type the user data
 onView(withId(R.id.edit_name)).perform(typeText(name));
 onView(withId(R.id.edit_lastname)).perform(typeText(lastname));
 onView(withId(R.id.edit_email2)).perform(typeText(email));
 onView(withId(R.id.edit_password2)).perform(typeText(password), closeSoftKeyboard());

 //if its a number edittext we have to use String.valueOf
 //also we need to closesoftkeyboard before and after, so it changes from text 
 //to number
 onView(withId(R.id.edit_age)).perform(typeText(String.valueOf(age)), 
 closeSoftKeyboard());
 onView(withId(R.id.edit_is_admin)).perform(typeText(admin), closeSoftKeyboard());
</code></pre>

after you perform typeText with edit text, close the soft keyboard as it may cover your view
by <code>closeSoftKeyboard()</code>
so full code be:
<pre><code> onView(withId(R.id.fab)).perform(click())
 onView(withId(R.id.edReminder)).perform(typeText(&quot;TestAA&quot;))
 closeSoftKeyboard()
 onView(withId(R.id.btnAdd)).perform(click())
</code></pre>
NOTE: using <code>closeSoftKeyboard()</code> with <code>perform()</code> not permitted as <code>perform()</code> accept ViewAction and <code>closeSoftKeyboard()</code> return <code>Unit</code>
use <code>ViewActions.closeSoftKeyboard()</code> with <code>perform()</code>.

I got a error when i run android espresso test:

<blockquote>

My code is easy:

<pre><code>onView(withId(R.id.btn)).perform(click());

But there is no error with this code:

</code></pre>

I can not find the cause why it happen.
