android.content.ActivityNotFoundException: No Activity found to handle Intent

代码如下：

public void sendMessage(String number) {
if (TextUtils.isEmpty(number)) {
return;
}
Intent intent = new Intent(Intent.ACTION_SENDTO,
Uri.fromParts(Constants.SCHEME_SMS, number, null));
context.startActivity(intent);
}

异常信息提示如下：

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.SENDTO dat=sms:xxxxxxxxxxx }

at android.app.Instrumentation.checkStartActivityResult(Instrumentation.java:1632)

at android.app.Instrumentation.execStartActivity(Instrumentation.java:1424)

at android.app.Activity.startActivityForResult(Activity.java:3424)

调查如下：

1,如果手机中没有能发送短信的app就会报出这样的错

2,手机中的能发送短信的应用被关闭了（设置-->应用-->app-->关闭）;

解决方法：为了避免有的手机没有打开相应文件的app,在startActivity那里做一个try catch

public void sendMessage(String number) {
if (TextUtils.isEmpty(number)) {
return;
}
Intent intent = new Intent(Intent.ACTION_SENDTO,
Uri.fromParts(Constants.SCHEME_SMS, number, null));
try {
context.startActivity(intent);
} catch(ActivityNotFoundException exception) {
Toast.makeText(this, "no activity", Toast.LENGTH_SHORT).show();
}
}

or 调用系统方法判断是否有对应的app

public void sendMessage(String number) {
if (TextUtils.isEmpty(number)) {
return;
}
Intent intent = new Intent(Intent.ACTION_SENDTO,
Uri.fromParts(Constants.SCHEME_SMS, number, null));

PackageManager packageManager = getPackageManager();
List<ResolveInfo>applist = packageManager.queryIntentActivities(intent, 0);
if (applist == null || applist.isEmpty()) {
Toast.makeText(this, "no activity", Toast.LENGTH_SHORT).show();
return;
}
context.startActivity(intent);
}
