How to solve the "No activity to process Intent" problem

Question

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=com.android.suven.Create_memo } 

I just want to move from one activity to another, but it gave me this error.

my main activity code looks like folllow

 @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); btn1 = (Button)findViewById(R.id.button1); btn1.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { try { Intent i=new Intent("com.android.suven.Create_memo"); startActivity(i); } catch ( ActivityNotFoundException e) { e.printStackTrace(); } } }); btn2 = (Button)findViewById(R.id.button2); btn2.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { try { Intent i=new Intent("com.android.suven.Create_memo"); startActivity(i); } catch ( ActivityNotFoundException e) { e.printStackTrace(); } }); } } 

My logcat looks like this:

Answer 1

in your code line

 Intent i=new Intent("com.android.suven.Create_memo"); 

"com.android.suven.Create_memo" is taken as ACTION.

Instead you need to put

 Intent i=new Intent(YourCurrentAivityName.this, Create_memo.class); 

Also add

 <activity android:name=".Create_memo" > </activity> 

in the AndroidManifest.xml file.

Answer 2

Have you declared Create_memo activity in the manifest file? as:

 <activity android:name="com.android.suven.Create_memo" /> 

Answer 3

This is NextActivity.java

 public class NextActivity extends Activity { //Your member variable declaration here // Called when the activity is first created. @Override public void onCreate(Bundle savedInstanceState) { //Your code here } } 

After creating a new action, we must register it in the file "AndroidManifest.xml". To register, we need to create an entry in "AndroidManifest.xml as

 **<activity android:name=".NextActivity" android:label="@string/app_name"/>**
