    <p>You can create a class derived from <code>std::streambuf</code> which uses the Android specific functions to send the produced sequence of characters. I don't know where the default implementation of <code>std::cout</code> sends characters on Android, however. Basically, this would look something like this:</p> <pre><code>class androidbuf : public std::streambuf { public: enum { bufsize = 128 }; // ... or some other suitable buffer size androidbuf() { this-&gt;setp(buffer, buffer + bufsize - 1); } private: int overflow(int c) { if (c == traits_type::eof()) { *this-&gt;pptr() = traits_type::to_char_type(c); this-&gt;sbumpc(); } return this-&gt;sync()? traits_type::eof(): traits_type::not_eof(c); } int sync() { int rc = 0; if (this-&gt;pbase() != this-&gt;pptr()) { char writebuf[bufsize+1]; memcpy(writebuf, this-&gt;pbase(), this-&gt;pptr() - this-&gt;pbase()); writebuf[this-&gt;pptr() - this-&gt;pbase()] = '\0'; rc = __android_log_write(ANDROID_LOG_INFO, "std", writebuf) &gt; 0; this-&gt;setp(buffer, buffer + bufsize - 1); } return rc; } char buffer[bufsize]; }; </code></pre> <p>To actually set up <code>std::cout</code> to write to this stream buffer, you would do something like this in your <code>main()</code> function:</p> <pre><code>int main() { std::cout.rdbuf(new androidbuf); ... } </code></pre> <p>This create a memory leak for the one <code>androidbuf</code> stream which is, however, somewhat intentional: the stream may be written to after <code>main()</code> is exited and it is flushed when when <code>std::cout</code> gets destroyed. If you don't want this, you could either restore <code>std::cout</code>'s original stream buffer or set it to null and delete the return from <code>rdbuf()</code>:</p> <pre><code> // avoid a one-time resource leak but don't get output afterwards: delete std::cout.rdbuf(0); </code></pre>

    1. COThanks for another solution. But it involves more coding, I'll try it later.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
