android.content.ActivityNotFoundException: No Activity found to handle Intent { act=com.android.suven.Create_memo }
我只想從一個活動去另一個活動,但它給了我這個錯誤。如何解決「找不到處理意圖的活動」錯誤
我的主要活動代碼是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();
}
});
}
}
我logcat的是這樣的:

條目你加你的活動在'AndroidManifest.xml'? – Shaiful
Hi @shubh您應該使用packagedecleration或不使用decleration將您的活動名稱添加到AdroidManifest.xml文件中。 – itsrajesh4uguys
